Seems quite rare, but I actually have some positive experiences to report when flying! I have just flown to and from Bucharest with TAROM, it was really quite passable. A cooked meal is served, even in economy, and it looks like a small company in Romania manufactured everything; no Gategourmet packaging here. The hostesses seem to not have been to some fake-smile training course. The plane was even a reasonably modern Boeing 737-700.
LHR was also quite reasonable – plenty of staff at security, so no long queues even with the new ludicrous security procedures. Then after check in I have finally managed to register for the Iris-Scanning system; this allows an automated check upon return to the UK, rather that queuing at passport check. Basically you walk into a booth, stare at the machine, and on you go. Upon returning to Heathrow, you walk into a booth, stare at the screen, your eyes are checked and on you go. Perfect. No queues!
