When I make a reservaion for flight/hotel is the money automatic taken out of my checking account?

Answer 1

If you're paying with a debit card, the flight is charged to your account as soon as you make the reservation; airlines want your money before they guarantee your seat. For hotels, it varies; if booking through a reseller like travelocity or priceline, the charge goes through as soon as you make the reservation but if you book directly with the hotel, sometimes it's charged right away and sometimes they just keep your number on file until you check in.
