Pros: Very helpful and courteous flight attendants.

Cons: Chaotic boarding process, like cattle all in one mass. Frustration of short transfer time exacerbated by failure of the scanners to accept the boarding pass, slow handling of passengers by gate personnel, lack of overhead storage required me to check a small carryon bag.

Pros: The in flight services met my expectations.

Cons: We were informed at the Nairobi check in that our tickets had been suspended because of possible risk of fraud. Attempts to resolve this promptly were not successful. For a first time traveler to the UK, this created unnecessary anxiety and gave us the feeling that the agency appointed to check us in are not supportive. We were eventually sorted but this is not nice at all given the fact that payments went through and tickets were issued and no one informed us of any issues until we got to the airport. Some feedback would be appreciated.

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.

We compile tonnes 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 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.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
