How to use this web check-in guide

Online check-in windows and airport cut-offs differ by airline and sector. Use the airline guide to find the correct timing, then confirm your terminal and baggage-drop deadline.

Check the opening window

Domestic and international check-in can open at different times, even with the same airline.

Allow for baggage drop

A boarding pass does not replace the airport baggage-drop deadline when you have checked luggage.

Common mistakes

Avoid these travel-day surprises

Treating web check-in as airport arrival

You still need time for baggage drop, security, immigration and any document verification.

Assuming every passenger is eligible

Infants, special-assistance bookings and some international routes may require counter check-in.

Understand the rules

Online check-in, baggage drop and boarding are different deadlines

Online check-in confirms passenger details and may issue a boarding pass. Baggage drop is the last time checked luggage is accepted, while the gate closes before departure. Meeting one deadline does not protect you from missing another, so work backward from the earliest published cut-off.

Check-in window

The period when online check-in is available, often beginning 24–48 hours before departure.

Baggage-drop cut-off

The final time the airline accepts checked bags; it can be earlier for international flights.

Document verification

An airport check of passports, visas or entry forms that may be required despite online check-in.

Questions answered

When does airline web check-in open?

+

Most airlines open it 24 to 48 hours before departure, but the exact window varies by airline, airport and international or domestic sector.

Can I web check in with checked baggage?

+

Usually yes. You must still reach the airline's baggage-drop counter before its cut-off.

Why did online check-in not issue a boarding pass?

The airline may need to verify a passport, visa, payment card or special-service request at the airport counter.

Can I change my seat after web check-in?

Do I need a printed boarding pass?
