Reservations with Finnair

Review a prospective Finnair trip on the airline website. If contacting a US phone route, check the local-number label and your calling charges before requesting reservations help.

Start a new booking

Compare flights on Finnair’s own website or ask its reservations team about an itinerary. Have airports, dates and the number of passengers ready.

Prepare the airports, dates and traveller details for the Finnair itinerary you want to book.
Review the final fare, included services and ticket conditions with the seller before payment.

Book on the airline website

Retrieve an existing reservation

Use the booking reference and passenger surname shown on your confirmation. A frequent-flyer membership number and a booking reference serve different purposes.

If another airline or a travel agency sold the ticket, check the confirmation for the company responsible for servicing it. Do not send your booking details to this directory.
