Try getting the flight status of the LHR-TBS flights - the website refuses to believe such a route exists!
It will give you the LHR-GYD but that's it!
I once met a chap from bmi Business Development. They mentioned that only a very small percentage of their bookings originate from the website. That got me thinking that they were therefore focusing their efforts on obtaining more bookings by other means; but I actually think that perhaps it's cause and effect. A crappy website prevents bookings (and it does prevent bookings sometimes!)
