I flew with Gulf Air about 3 weeks ago in Biz on the London-Bahrain- Manila route and I can say that they were absolutely fine. They are not comparable to Qatar or Singapore Airlines but then I had paid far less for my ticket than with those airlines. The lounge in Heathrow is comfortable as is the one in Bahrain where I had an 8 hour layover. I enjoyed the onboard food and the wine was ok. Seat was comfortable and cabin crew were friendly if a little too eager to get dinner served on one of the legs. I had to tell them several times to wait before bringing my next course. Little things onboard need fine tuning but my only real criticism would be the very poor selection of films. The IFE really does need some improvement.. If the price was right, I would not hesitate to fly with them again.
