OK 5.3

Pros: Meal options and snacks, good crew staff. And relatively comfortable seating. The plane waited for us because of the earlier delayed flight, though we prefer to have been given the option to stay the night and catch the next morning flight.

Cons: The flight got delayed from Alexandria and the staff at Manama airport directed us to a counter to get our onward boarding passes but another senior member of staff asked us "what are you doing here" and asked us to go straight to the gate, then when we arrived at Abu Dhabi the baggage did not arrive with us and we had to go back to the airport later to pick them up.

Cons: Unfriendly ambiance. Disorganized boarding. I’m even a member of Fly Smiles. The flight attendant named Chanaka moved 2 old passengers on my side. I kindly requested to another staff if I can just move seat too because I am not comfortable. But request no action. The cabin crew are not that caring because I took care of the 2 passengers. I just don’t understand why they are unfriendly. I will not choose this airlines again.

It is also not clear that I need to book a hotel thru the airline during my 13 hours transit. I was thrown back & forth like a ball. No help was done. How come an airline imposed such rule?! Worse part during flight I feel cold & asked for a blanket. We reached destination No blanket ever!! Not recommended. First & last!!!

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

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons of data for you
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 don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.
