Maybe they should have a shuttle service to carry the F passengers all the way from the tube to the check in area.
On the only occasion I flew CW from T5 the taxi driver dropped me at the relevant door, nice chap that he was!
It's a shame that even when flying at the front of the plane people still have to complain, think about those of us less fortunate than yourselves, we don't have to walk as far to check in, but we have to walk the length of the plane!

And run the gauntlet with the rest of the world in Wetherspoons!
