Pros: I particularly liked the seating which even in economy was roomy and comfortable. The air hostesses were very helpful and pleasant.
Cons: I don't like drinking hot beverages out of paper cups! Even plastic is preferable to paper. The whole eating experience felt a bit picnicky - boxes of this and that. And I didn't like getting a freezing cold ice lolly in the middle of the afternoon - being British I was longing for a cup of tea and a biscuit or piece of fruit cake. The worst of all was being given late in the afteernoon a cold/damp wrap full of soggy cheese and tomato. Give me a traditional sandwich or roll any day.

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