Examples of Ajax-based reservation (hotels/flights/car rental) sites

Does anybody have an example of the web-site for
ticket/flight/hotel/car reservation with one-page interaction model,
possibly based on Ajax? That means the user doesn't have to fill out
the form in several steps, instead, he can select everything he wants
on one single screen.

The Broadmoor Hotel Reservation
https://reservations.ihotelier.com/onescreen.cfm?hotelid=2054&languageid=1

is a well know example. Are there similar sites?

Thanks in advance,
