•In the event that we have to change your seat we will endeavour to seat you in a suitable alternative. We will look to seat your party together in the first instance, and then if possible in your choice of window seat, middle seat or aisle seat. If you have paid for an exit row seat we will look to seat you in another exit row seat. If you are not completely satisfied with your replacement seat you are eligible to apply for a refund. Seats are not transferable to any other passengers.
