I use old Travelocity interface.

This doesn't have any ads on the page. Only problem is you may have to reload the page until you get the interface.

Travelocity seems to begin favour some airlines. When I checked ARN-NYC price, I found that LX, BA and some other which have more expensive price than SK, LH etc come top part of the fare list.
