Stewardess seems very annoyed with flight. There was turbulence so the passengers needed to stay seated - a gentleman next to me asked for a glass of water since there was no refreshment service - the stewardess was very short with him. It’s not the passengers fault. I was surprised - usually the staff is a lot more professional than that.

I had to stay at Beijing for overnight and took a flight the next day.

Okay 5.6

The style of the pillows and blankets were nice. The pillows were really comfortable and a good size. The taste of the food was okay. I honestly expected a horrible experience, it was not fantastic but it was better than what I anticipated.

The sealed blanket had white hair as if from an older person. Although I liked the pillow, on my return flight I used it to sleep, I used it for my back the entire time going, when I got home I noticed I was developing a sty on my eyelid. My companions noticed that the sometimes when he received his food it was still cold in some parts. On my return flight there were a few times my row was skipped for drinks. On my return flight the stewardess seemed hesitant when I asked for an additional drink. I ordered tea and asked for water. The gate agent in Beijing was extremely rude and unhelpful, she ignored us and even tossed our ticket back at us when we tried to ask about our seats for the flight.

One of the flight attendants was nice.

AA is now trying to save money (presumably) by doing like Delta: forcing half of us to connect in Charlotte. Unfortunately, the Charlotte airport is not ready to accommodate so many people. The airport looks like it is being renovated, which is fine, but there is no tape/cones to mark off the renovated areas from the walkways. You literally walk through dirt and construction sites. I didn't even think that was legal in the US?! Anyway, maybe it will be worth it once the renovations are complete, especially if AA is going to use it as a hub.

I'm not sure where the problem was - whether with AA or Royal Jordanian, but my luggage did not make it to Amman with me. In fact, there was a whole group of passengers traveling on American from different US cities, switching to RJ in Chicago, whose luggage did not come on the flight to Amman. My advice: be sure to pack enough for a couple of days in your carryon - and don't accept an offer to check your carryon to its final destination!

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,
