re: TAP
Flying to/from Lisbon with TAP is hard work given the distances involved at the Lisbon end. Last June, coming back from Lisbon, we checked in then had to walk the full length of the terminal to the very last gate, then we were put on a (filthy) bus and driven right along all the gates we had walked past and across the airfield to the aircraft. Much further to walk then flying from Dubai, Heathrowe T3, Manchester etc. FR may well manage to do it better.
