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.

My husband and I chose seats together when the tickets were purchased and when we received or boarding passes they had been changed, separating us. My 6 foot 200 lb husband ended up against the window in a row with 2 women that were both well over 250 lbs and I was seated with strangers. No free movie as there was on the trip to Texas

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!

Ok, I get that I checked in on the first half of the round-trip too late to get a cheaper rate for checked baggage, why I charged the increased amount for return flight made no sense. Also it would have been nice to know that you needed to check in more than 24 hours in advance to avoid the baggage surcharge. No party to this transaction bothered to tell you.

It was short

Completely full plane. Ridiculously tight seat pitch. Overhead bins full. 45-minute delay for a dead-heading flight crew. Long wait for checked baggage. No beverage service because of turbulence. Flight crew out of position is a management problem, don't make it an inconvenience for a 737 full of paying passengers!

I am used to flying Frontier because of cost but recently traveled Delta and boy did I feel completely spoiled! Not only did my other half get our bags for free due to his status with Delta but the amenities they offer and the comfort of the economy seats compared to other airlines is a major difference. As a chronic pain patient, if I can find a Delta flight for a little more, I will be booking with them for sure! Highly recommend them!

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.
