Flight was without any hitches, could have done better with boarding after the previous mishap of a 5 hour delayed flight and being forced to stay in Doha for a night which put everyone's schedules off by a day. Still, I would book another flight with Qatar airways for their efforts and overall good service.

It would have been nice if Qatar Airlines also provided Priority Boarding for everyone on the flight that got delayed as there was a long line just to get to the boarding area.

Cabin was very nice with modern equipment and food and refreshments were provided frequently. Entertainment options were great too. Cabin crew were very pleasant.

Connecting flight from Philadelphia to Doha was delayed by 5 hours due to some technical errors. By the time we arrived in Doha, there were no more planes heading to Manila. We did get booked a free night's stay in a hotel in Doha along with transport to the airport

Plane was new and very nice.

Kuwait airport is extremely un organized. Also you cannot upgrade your ticket as the staff in Kuwait are not able.

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,
