heathrow is a nightmare, and avoid british airways like the the plague they have the worst customer service and the rudest staff as well as the most nazi like rules about carry on unfortunately they are hard to avoid in that part of the world, lufthansa are not too bad singapore airlines are great as is cathay
Yeah, unfortunately I know. Heathrow is just awful. I still kept taking that route because for a number of years they were just the cheapest on my routes out of Boston and to continental Europe. But still, the stuff that happens to luggage there and the delays and the busing people around and the security-kabuki dance (resulting in missing connection flights)...
Lufthansa, generally speaking, I like but they now also have some 8kg policy in place and ze Germans may just be disciplined enough to actually enforce it now. Same with Iberia. Had good experiences otherwise including connecting at Madrid airport.
Singapore Airlines may be something to check out. Never took them but heard good things. I think they go into Frankfurt from here which would work for me.
