Pros: Never seen such a large streaming movie library. Never seen live stream at seat from cameras (3) outside the plane.

Cons: It was not clear this was a no-checked-baggage flight, seeing as I specifically searched with flights with luggage. I chose Lufthansa's flight counting on the fact that international flights always allow one checked bag. I had to pay on that way here. I"ll have to pay on the way home.

Pros: The turkey sandwich was okay.

Cons: I was seated next to an extremely large man. I possessed only half of my seat for the duration of the six hour flight. I asked a flight attendant to move me but she said the flight was full. There should be a protocol for passengers over 300 lbs.

OMA
LGA
Poor 0.0

Pros: Nothing. Delta cancelled the flight with no explanation, and ruined our last day in Omaha.

Cons: An explanation as to why the flight was cancelled, as well as help with finding alternative accommodation. We had to fly back very early via Atlanta, and spent the day in transit, which forced us to cancel a reservation in Omaha and erased our ability to enjoy the final day of activities there.

Good 7.2

Pros: Crew was great.

Cons: When all overhead bins were full, they should have allowed those who didn’t need to check their carry on to board the plane before those who needed to check their carry on. Very unorganized at gate.

Pros: Service manager Alan and crew were lovely, very friendly and felt genuinely happy to help us. I have never been given so much free stuff on a plane before! The snacks and beverage offerings just kept coming. I enjoyed my warm meal. Entertainment offerings were good, and as we were on a newer plane the technology was better than other flights I’ve been on.

Cons: Seats could have been a bit more comfortable and roomy, but they were decent and I didn’t have too much trouble sleeping.

Prices are per person, are for e–tickets and include all taxes & fees in EUR.

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 hires 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,
please send us an and someone from our team will get back to you promptly.
