I chose Oman at the last moment because my agent got a good deal for me. honestly I didnt have very high expectations from them, but, it turned out to be a good experience overall. I traveled economy and it was as cramped as it is on most carriers these days. So the long haul Muscat-Manchester route was tiring. The food and drinks menu wasnt very elaborate but the portions were fairly sumptuous, and they obliged with repeat drinks. The in-flight entertainment was average, but the quality of their ear-phones is pathetic and many of them dont work, and you wont even get a replacement easily, especially if the flight is full. Better to carry your own earphones.
Best part of the flight was :
1. its convenient timing from Delhi to Manchester via Muscat - 10am departure from Delhi and 7pm arrival in Manchester, so you dont have to stay awake in the night.
2. Muscat has a brand new airport and not very crowded so there are plenty of recliners to rest.
