How do I add baggage and pre book seats with Sun Express?

Modified on: Fri, 14 Nov, 2025 at 3:28 PM


Our holidays with SunExpress flights all include 1 carry-on cabin bag up to 4 kg as standard, with a size of up to 40cm x 30cm x 20cm.

If you’ve already booked and want to add baggage, seating or even a meal, you can. You'll need to log on to the SunExpress website and pay them directly. We've dropped a link below to take you there but you might find it helpful to read these instructions first. And, just so you know, any flight extras you add directly with SunExpress won’t show on your Thomas Cook invoice / confirmation.

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

 

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

Or:

  • Lead passenger surname
  • Your payment card details

Click through to SunExpress using the link at the bottom of this page, and click into the 'SunExpress bookings' tab (shown below). You'll then need to enter your surname and airline reference (as above) in the section named 'booking number'.

You can then access your booking to choose and pay for any extra baggage, pre-booked seating or in-flight meals (see example below). Remember, you'll need to pay SunExpress in full for these.
