thats a shame. ive done BA from LGW for three weekends recently both morning and afternoons. i was shocked on the bank hols friday to arrive to a ghost airport...there were a total of three people in the entire checkin area of BA in line and security was equally empty. the other two were also incredibly empty and it was all so civilized and wonderful.
but as noted above i can see how going into summer things will probably unravel at LGW like at LHR too.
