Smart Check-In: When Check-In Opens and Closes for Your Airline

On this page

Every airline opens check-in at a different time. American opens 24 hours before departure, Lufthansa 30 hours, Emirates 48 hours and easyJet 30 days. Cut-off times differ too, and often change between domestic and international flights. Smart Check-In in Tineo puts the right numbers on the flight itself: a Check in button that shows when check-in opens and closes for your airline and route, what the airline says to know, and one tap to the airline’s own check-in page.

Smart Check-In is part of the next Tineo update for iPhone, so you can download Tineo from the App Store and turn on automatic updates to get it when it lands.

A Check in button on every flight

Flight cards now carry a Check in button with the airline’s logo, next to More and your other flight actions. It is there from the moment the flight is in your trip, not only once check-in is open, so you never have to hunt through a menu for the link. The Minimal timeline shows the same button as a small chip under each flight.

Know when check-in opens and closes

Tap the button and it opens into a panel on the flight. At the top it says when check-in opens for your flight, with the date and time, or Check-in open once it is. Below that it lists the opening time, the closing time and whether the airline’s app can check you in.

Tineo also sends you a notification when check-in opens for a flight, so you don’t need to set an alarm for 24 hours, 30 hours or 30 days before.

Windows that match your airline and your route

There is no single rule. Tineo keeps a check-in window for each airline and, where the airline publishes different rules, for domestic and international flights. A few examples, as published by the airlines in Tineo’s data on November 5, 2026:

Even within one airline the answer can change with the flight:

Treat the table as a snapshot. Airlines change their rules, and the airline’s own page is always the final word.

Airline notes, in plain words

Under Good to know, the panel carries up to three notes from the airline, such as “Must check in at least 30 minutes before departure (45 min with checked bags)”. Where an airline sells early or paid check-in, the panel says so. The same panel opens from a flight in the plan sheet, so the notes are one tap away wherever you meet the flight.

One tap to the airline’s check-in page

When you are ready, tap Check in in the panel. Tineo opens the airline’s own check-in page, where you finish check-in and get your boarding pass from the airline. Tineo does not check you in itself.

For 14 airlines, Tineo can open that page with your booking details already filled in. For the rest, you enter your booking details on the airline’s page. 152 of the 189 airlines Tineo researched have a direct check-in link, and 131 of those links were opened and confirmed in a real browser.

Connecting flights get one button per airline

If your journey has connections on different airlines, Tineo shows one Check in button per airline, starting from the first flight that has not left yet. A trip with one airline for the first leg and another for the second never leaves you checking in with the wrong one.

Dark mode, large text and right-to-left languages

The panel follows your appearance setting and your text size, and mirrors for right-to-left languages such as Arabic and Hebrew.

What is behind the numbers

Smart Check-In runs on a dataset Tineo built from the airlines themselves.

• 189 airlines researched, 166 with a check-in window verified against the airline’s own pages.
• 303 cited sources, 288 of them official airline pages, so each rule traces back to something the airline published.
• 152 direct check-in links, 131 of them opened and confirmed in a real browser.
• Regular rechecks of the check-in links, so a moved page does not send you to a dead end.

For airlines without a verified window, Tineo does not present an opening time as the airline’s rule.

How to use Smart Check-In
