You can request specific bedding types under the room preferences on the "Traveler Information" page. Suppliers will try to accommodate your request, but because availability varies, your request cannot be guaranteed. The default bedding is generally a double bed.
Until you have completed your booking, airfare is not guaranteed. The airline may change the fare and seats may become unavailable (also resulting in a price change).
Each airline has its own policies regarding the acceptance of unaccompanied children. Please contact the airline directly in order to book a flight for an unaccompanied minor.
Some airlines choose only to show a portion of the seating and some choose not to show anything at all. The remaining seats can be seen at the airport upon check-in.
