Online Check-In Times by Airline (2026): When It Opens and Airport Cut-Offs

Open your booking: it shows when check-in opens and when bags close. We are an independent guide, not an airline. Check in only on the airline's own website or app, or at its airport desk.

Key facts

• Online check-in: 24 hours before departure at Air Canada, Delta, Frontier, JetBlue, Virgin Atlantic and WestJet (read on the airlines' own pages on 9 Nov 2026). American and United say the same on their own pages (read 14 Nov 2026).
• Earlier windows: Emirates 48 hours and easyJet 30 days (read 9 Nov 2026); Lufthansa 30 hours, KLM 30 hours (24 on US flights), Qatar Airways 48 hours (24 on US routes), Ryanair 72 hours with a random seat and up to 60 days with a reserved seat (read 14 Nov 2026).
• Airport cut-off: 45 minutes for bags on US domestic flights at Delta, United and JetBlue. Frontier closes check-in and bag drop 60 minutes before departure; Ryanair has closed airport check-in and bag drop at 60 minutes since 10 November 2026 (40 minutes before that); Air Canada closes check-in at 60 minutes and bag drop at 45 minutes within Canada. Most international departures need 60 minutes. Airports can set longer times.
• Gate: separate from the check-in cut-off and often 15 to 30 minutes before departure.
• Missed cut-off: the airline can cancel your booking or refuse boarding, and US rules do not give denied boarding compensation for it.

Check-in times by airline

Each row links the airline's own page and the day we read it (9 or 14 November 2026). Lufthansa's 30 hours is from lufthansa.com (14 November 2026); the rest of its row comes from our Lufthansa guide (31 October 2026). Alaska's cut-off page would not load for us, so that row gives only the 24-hour opening and no cut-off. A dash means the airline does not publish the figure on that page.

Check the time on your own booking or boarding pass before you leave. Airlines print airport-specific closing times there, and several of them, including Delta, United and Lufthansa, say outright that some airports differ from the default. If the airline cancels instead of you missing the cut-off, our pages on Air Canada, Qatar Airways and Air France cover refunds.

Delta: 24 hours online, 45 minutes for bags on most domestic flights

Delta lets you check in on delta.com or in the Fly Delta app up to 24 hours before departure (Delta: how to check in), and the app checks you in automatically at that point when you are logged in. For domestic flights Delta says bags must be checked at least 45 minutes before departure at most airports, and passengers without bags must be checked in 30 minutes before. Everyone must be at the gate and ready to board 15 minutes before departure, and Delta will not take checked bags at the airport more than 6 hours ahead.

Some airports need more, and Delta publishes the airport list on its domestic check-in requirements page. That list shows 60 minutes for bags at New York JFK and 90 minutes at St. Thomas, and 45 minutes even without bags at Las Vegas, Miami, Honolulu and several others. On international departures you must be checked in at least 1 hour before, longer at airports such as Frankfurt and Dublin (75 minutes), and Delta says you "will not be permitted to check in after that time." What you pay for bags is covered in our Delta baggage fees guide.

United: 24 hours online, 30 or 45 minutes on domestic flights

United opens check-in 24 hours before departure on united.com and in its app. Its check-in time limits page (read 14 November 2026) says to check in at least 30 minutes before departure without checked bags, 45 minutes with checked bags and 60 minutes on international flights. Press reports from 27 May 2025 (Time Out) said United would raise the carry-on-only domestic limit to 45 minutes from 3 June 2025, but united.com still shows 30, so go by United's own page and your boarding pass.

United's own check-in time limits page lists the airports and routes with longer limits.

Special limits apply: the same United page lists 90 minutes for flights to or from Micronesia and the Marshall Islands, for Saipan, and for international flights from Honolulu. United warns that "we have the right to deny service which may result in cancellation of your reservation, denied boarding or the option to check your bags" if you miss them.

KLM: 30 hours online, 24 hours on US flights

KLM opens online and kiosk check-in 30 hours before departure, or 24 hours before flights to and from the United States. At the desks, check-in closes 40 minutes before European flights and 60 minutes before intercontinental flights, with longer closing times at a few airports (120 minutes at Accra and Lagos, for example).

At Amsterdam Schiphol, KLM says baggage can be dropped in departure hall 1 between 04:30 and 20:00 and in departure hall 2 between 04:30 and 22:00, and that the closing time for drop-off is printed on your boarding pass.

KLM also says some passengers cannot check in online or at a kiosk and must go to a desk: those who requested assistance, travel with a pet or check in an unaccompanied minor.

What search answers get wrong

Can I check in online for an international flight?

Yes, with the airlines in the table, but the airline may ask for passport and visa details first. Delta says "International travelers also need additional documentation", and United tells you to have the passport or visa ready before checking in. Some airlines close online check-in earlier on international flights: American stops at 90 minutes before departure instead of 45, and Emirates closes online check-in 90 minutes before departure for e-ticket passengers.

If the airline cannot verify your documents online, you finish check-in at the desk, and the airport cut-off still applies. Air Canada also asks for an address where you will stay when you check in online for a US trip. Another US-bound detail: you clear US Customs and Border Protection in Canada before departure, and from Toronto Billy Bishop it asks you to arrive 90 minutes before departure to allow for pre-clearance.

Why can't I check in online?

The usual reasons are on the airline's own help pages, and most are fixed at the airport:

• Another airline operates the flight. Air Canada says that if the first flight of your itinerary is operated by another airline, you check in with that airline. WestJet lists partner-operated flights, and Lufthansa online check-in does not cover codeshares "operated by another airline"; see our Lufthansa check-in guide. Check in with the operating airline.
• A special request on the booking. WestJet names special service requests and recent changes; KLM names requested assistance, pets and unaccompanied minors. Air Canada lists the same groups (children travelling alone, medical assistance or a wheelchair, any special request, a pet in the cabin or hold) and adds that you need an airport agent for your boarding pass if you start your trip in Algeria, Cuba or Morocco.
• Documents need a person to check them. WestJet lists "additional verification or documentation", and JetBlue says a visa or residence document you believe you do not need must be resolved at the ticket counter.
• An infant with their own seat. easyJet says you may not be able to check in online and should check in at the airport at least two hours before the flight.
• Not all airports allow a mobile boarding pass. United says online check-in is available everywhere but not every location allows a mobile pass.
• It is not open yet, or it has closed. Check the table: the window runs from the opening time to the airline's online cut-off.

Is bag drop the same as check-in?

No. Check-in gets you a boarding pass; bag drop hands over your suitcase. Many airlines set one deadline for both, but several set two: Air Canada closes bag drop at 45 minutes within Canada while check-in closes at 60, and JetBlue takes domestic bags at 45 minutes but boarding passes at 30 at most airports.

If you have no bags, a mobile boarding pass usually lets you go straight to security. Ryanair says its passengers who do not check in a bag "continue to check in online" and go through security to the gate, while WestJet's airport kiosks only print bag tags and boarding passes, so WestJet guests check in online or in the app first.

What happens if I miss the cut-off?

The airline can cancel your booking or refuse to board you, and you will usually have no right to compensation. Air Canada says missing its deadlines may lead to "the reassignment of any reserved seats, the cancellation of reservations, and/or ineligibility for denied boarding compensation". Virgin Atlantic's conditions say it may "refuse boarding, cancel your reservation or change your seat" and will not refund the unused flight.

The same rule applies on US flights: a passenger who does not comply with the carrier's check-in provisions is not eligible for denied boarding compensation under 14 CFR 250.6(a), as our guide to being bumped from a flight explains.

If you are running late, contact the airline through its app or website before departure rather than after you have been marked as a no-show. What a rebooking costs depends on your fare.

Fake check-in numbers

Searches for airline check-in times are full of documents and forum posts that print "check-in helpline" numbers, and these are not the airlines. Use only the airline's own website, app or desk; how fake airline helplines work explains how to tell them apart.

Airlines change these times, often at single airports. Use the table as a starting point; your booking or boarding pass has the last word.

FAQ

When can I check in for my Ryanair flight?

With a randomly assigned seat, Ryanair's help centre (read 14 November 2026) says check-in opens 72 hours before your flight and closes 2 hours before. If you reserved a seat, you can check in up to 60 days before departure, as long as both flights of the booking fall within that window. Since 10 November 2026, airport check-in and bag drop close 60 minutes before departure, instead of 40.

Can I check in at the airport instead of online?

Usually yes, at a kiosk or a desk, but the airport cut-offs in the table apply and some airlines treat it differently. WestJet kiosks only print bag tags and boarding passes, so WestJet wants you checked in online first. Delta, JetBlue and KLM all offer airport kiosks where you can check in and print a boarding pass (KLM notes that not every airport has them).

How early can I drop my bags?

It depends on the airline. Delta and JetBlue accept bags no earlier than 6 hours before departure (4 hours at JetBlue's Fort Lauderdale and San Juan), Air Canada 4 hours before departure within Canada (3 hours on US and international flights, 4 hours at Athens, Lisbon, London Heathrow and Rome Fiumicino), WestJet up to 3 hours at most locations, and Avelo from 2 hours. Emirates lets you drop bags 24 hours ahead when you depart from Dubai, and 12 hours ahead on flights to the US.

What is the 24 hours counted from?

From the scheduled departure time, where an airline says so. Emirates says online check-in opens 48 hours before "your flight's scheduled departure time", and Air Canada says its check-in and bag deadlines are counted before the "scheduled departure time". Delta says "up to 24 hours before departure". None of the pages we read says whether the clock follows the local time at the departure airport, what happens if the flight is delayed, or that check-in opens at midnight, so we do not state it. Your booking or app shows when check-in opens for your flight.

Which airline do I check in with on a codeshare flight?

The airline that operates the flight. Lufthansa says its online check-in does not cover flights operated by another airline, WestJet says online check-in may not be available on partner-operated flights, and Virgin Atlantic notes that check-in deadlines for other carriers operating your flight can be different.
