On arrival on 10th Sep at SFO, I found one of my checked-in baggages was missing. This made me bit worried. I made a complaint to airlines staff there. Some inconveniences caused since I kept my needed cloths in that bag.

They canceled my flight without an email confirmation. I went to the airport to find out it was canceled then to get an email now asking how my flight was when I couldn’t go.

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.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

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

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

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.
