for a tall guy you need to raise the seats a bit; the food was better than most airplane food but overcooked rice and fish was meh ... it's hard to image how an industrially prepared food could be better, but until you figure it out I'll keep packing my lunch

My first meal offered a lamb and rice dish with carrots and currants that was most tasty, while the second meal included a nice vegetarian rice dish. They were both very good and a good introduction to the wonderful food of the Middle East.

I had an issue with the sound on my entertainment unit that caused it to stop every time I paused a viewing. I had to exit then return to the show, which restarted where I paused it, but it was annoying. It also would have been nice to have a solitaire card game to play online. Overall, though, the variety was well thought out.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
