British Airways is having a sale. For some weird reason, it seems you have to fly through Chicago but for my relatives, that wouldn't a problem (hint, hint). The travel is valid from October 22, 2009 through March 28, 2010
These aren't the cheapest tickets I have ever seen but they are definitely on the low side. These tickets seem around $200 per leg. We have flown British Airways a couple of times and had a pretty nice flight.
