The flight did eventually take off, unlike a few others leaving around the same time.

We were delayed several hours and were never told why. Mostly there were no Aeroflot staff at the gate to ask. When there was, they said they couldn't help us because our flight was a codeshare with FinnAir. At the last minute they switched gates, sending us all scurrying.

Liked: that it didn't crash, I guess.

Didn't like: we had to beg for water from the staff (there and back) just because we didn't pay for a meal. We didn't even get offered snacks on either flight. One way was 13 hours and the way back was nearly a 12 hour flight. There was also no wi-fi, and even though this is a first world problem, it's 2018 and the flights were longer than some people stay awake in a whole day. That's ridiculous. Kayak is chill, but Norwegian will no longer be an option for my travels.

Nothing notably. One would assume price but it wasn’t particularly different than non budget airlines. I didn’t know Norwegian was a budget airline until I got to my destination and was complaining about how bad my traveling experience was and they told me it wasn’t because Norwegian is a budget airline.

I had a backpack and duffel back for an 8 day trip overseas. I get this is a budget airline but Ryan Air works because the sacrifices make sense given the distances they travel aren’t hours. Shoving people on a flight like that with tight space, no food, no entertainment and charging me $65 for a duffel bag that you force me to check because I’m carrying 11 kilos in two small bags? Pass. Costing $50 less is far from worth it and I regret not opting for british or pretty much any other airline.

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!

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.

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.

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!

I paid almost $400 for upgraded seats. When I got to the airport-- no seats-- both ways!! i didn't even have regular seat assignments. I had to choose from the last few seats available. The ticket agent, the gate agent and the cabin crew all did nothing to make up for the fact that their system screwed up and stuck me in a cramped coach seat in the back of the plane for 11 hours-- TWICE! Beyond that, KLM must have one of the oldest fleets in the sky. Both ways LAX->AMS->LAX, I was on a 30-35 year old 747 with no wifi, no power and a ten-year-old entertainment system. Never again.

I flew out with the same luggage that I flew in with. They charged me $56 for it. It seemed as if they made a new rule out of the blue and included my personal bag my carry on. It wasn't that they had to be concerned about the FAA weight requirements because the flight was only about 80% full. The in-flight entertainment was limited and there was no audio... so in other words, you could not simply turn on music to go to sleep by. This is a very bare-bones airline. Also, one flight attendant was perhaps the rudest person I've ever come across. "Go talk to someone else - I'm busy." All I asked for was a fork. She was simply opening a bin at the moment.

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.
