Upgrade to Select Your Seat* to choose where you sit on the plane. Secure your ideal seats from a map during the booking process by choosing Select Your Seat or buying any seating upgrade. Or, do it after you’ve booked via Manage My Booking. You can also upgrade in your local TUI Store or by calling us on 01 693 7700 (ROI) or 028 90 389 387 (NI). Plus, by upgrading to Select Your Seat, you get the benefit of early online check-in. It’ll open 14 days before your departure, instead of 48 hours. Just so you know, you’ll still need to check in for your outbound and inbound flights separately.Just so you know, seats 1A, 1B, 1C, and 2D, 2E and 2F on our 737 aircraft fleet are narrower than other rows, the armrest is fixed and the tray table stows inside it. These seats may not be suitable if you're using an extension seatbelt.If you can’t decide where to sit, check out this 360-degree virtual tour of our Dreamliners. Just so you’re aware, children under 12 will be seated with at least one adult from your party, which could be in the same row, one row in front or behind, or across the aisle. This should be sorted automatically when you check in, but if not, please give us a call on 01 693 7700 (ROI) or 028 90 389 387 (NI). *For full terms and conditions, visit the “Select Your Seat” section of our A to Z guide.
