Automatic flight check-in

Never miss a
check-in again.

The free window seats are gone four minutes after check-in opens, and after that the airline sells you one. Aisle is there at second zero, on every flight you book.

Works with 240+ airlines

The seat fee

Airlines sell the seat
you could have had free.

Seat selection is one of the most profitable lines in European aviation. It works because nobody is awake at the exact minute check-in opens, when the same seat costs nothing. Aisle is awake every time, and never spends a euro without asking you first.

Published standard seat-selection ranges, economy, one way, mid 2026. They move constantly, which is rather the point.

T + 0s

Aisle is already inside

Queued before the window opens, submitted the moment it does, while everyone else is still loading the app.

T + 4min

The windows are gone

On a full narrowbody the good seats disappear in single-digit minutes, usually while you are asleep.

T + 40min

Pay or take a middle

What is left is a middle in the back, or the airline's fee to get out of it. Nobody chooses this, people just check in late.

Answer once. Window or aisle, front for a tight connection, extra legroom past four hours, never the row by the toilets. It holds on every booking, on every airline.

Trust

We are asking for access to your travel. Here is exactly what we do with it.

Read-only, scoped access

Aisle reads flight confirmations. Not your inbox, not your contacts, not your bank. Revoke it from your provider whenever you like.

Credentials in a vault

Airline logins are encrypted at rest with per-user keys. Never written to logs, never visible to our team.

Nothing sold, ever

No ad networks, no data brokers, no affiliate seat upsells. You pay for the service, that is the entire business model.

A human behind it

If an airline blocks the automation, a person on our team finishes the check-in and tells you what happened. Before the airport does.

Questions

The ones people
actually ask.

What if check-in fails?

Aisle retries immediately, then escalates to a person on our team. You get a message telling you exactly what happened and what to do. You are never surprised at the gate.

Will it ever pay a seat fee for me?

Never without asking. Aisle takes the best free seat the moment check-in opens. If the only way to match your preference is a paid seat, it messages you the price first and waits for a yes.

Do you need my airline password?

Only for carriers that require an account to check in. Those credentials live in an isolated vault with per-user encryption keys. For most airlines a booking reference and last name are enough.

What about people I travel with?

Add companions to a trip and Aisle checks everyone in together, keeping the party in the same row or as close as the cabin allows.

Which airlines work?

240+ carriers, including every major European low-cost airline and all US legacy carriers. If yours is missing, tell us. It usually lands within two weeks.
