The best way to add baggage and seats with British Airways is during your holiday booking journey on our website.

BOOK FLIGHT EXTRAS

If you’ve already booked and want to add these on, you can. You'll need to log on to the British Airways website and pay them directly. We've added a link above and below to take you there but please read on to help assist you in adding on your flight extras. Just so you know, if you're adding any flight extras directly with the airline, they won’t show on your Thomas Cook invoice.

Make sure you have the following handy, as you can't access your booking without it!

• Your flight reference found on your invoice/confirmation. This is not your Thomas Cook booking reference. You’ll find it in the flights section of your Thomas Cook invoice, labelled either Airline reference or Flight booking number (depending on when you booked your holiday), as shown below.

For example:

Or:

  • Lead passenger surname
  • Your payment card details

Once you’ve clicked on the link at the bottom of this page, enter your surname and, in the section named 'booking reference', add your airline reference (see above).

You’ll then have access to your booking where you can choose and pay for any extra baggage you need and add pre-booked seating. Any changes you make here will need to be paid in full to the airline directly.
