We arrived at the airport 2 hours before flight time, got ready to check our bag only to be told our flight to Phoenix had been cancelled and there was no replacement flight available until Friday - this was on Monday. No assistance to get us on another airline, just no customer service. We found another flight which cost double our fare and waited 12 hours in the airport— they didn’t even offer to buy us breakfast.

I got there safely.

I will never fly American Airlines again. From the moment I checked in with the ticket agent to getting off the plane it was a disaster. The ticket agent was rude, hostile, and dismissive. Employees walked through the line at security forcing everyone to consolidate their belongings to one bag. I had a large wallet in my hand and was told I had to step out of line to put it in my backpack. They only allow you one bag to carry on without paying extra. At the time of boarding they announced that the overhead storage was full so even those that paid extra were still forced to check their bags. The plane was dirty, the service was slow, overall just gross. They don’t have WiFi or in flight entertainment so I paid the $20 to purchase the WiFi. It was worthless. I couldn’t stream anything, even music kept stopping to buffer. I understand it will be slower then on ground WiFi, but it was impossible to watch anything and a complete waste of money.

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.

The crew was lovely. Really nice, and did a wonderful job with the cart service.

We ended up being deleyed about 30 minutes, in damp weather. It's not like it was snowing. Not sure why it took so long. B/c of baggage charges now everyone brings a carry on. This seems to slow the process of boarding as know passengers are asked multiple times to check baggage (for free, which is the one nice thing) before boarding b/c the overheads will be too full. Group 6 which I was in seemed like it was just the rest of the plane. Super busy, took me forever to get to my seat all the way in the back. Why don't airlines reverse board? People sitting in the back should board first. I feel like this would save so much time.

For a little over $2000 you get an economy seat non-stop from DC to Tokyo and back. Meals were good. As economy seats go, it's comfortable. Midweek the flight is about half to two thirds full. So you might be able to stretch out even!

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.

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.
