Which is the cheapest way to get Bayswater from Luton aiport? We are an
adult and two 14 years old children.

Greenline coach 757 (same as Easybus) from the airport to Marble Arch
(timetable can be accessed from the Luton Airport website) and then a
bus (there are several routes) to Bayswater. But if you have luggage and
children, it might be worth getting a taxi from Marble Arch - its only a
short distance.
