Mediocre 2.0

Pros: None of the above. I actually liked nothing about this trip. Took off at London in time for Frankfurt, arrived early, but missed the connection to Tel Aviv. So I had to be routed to Munich to catch a 10:30 pm flight, which arrives at 3 am Sunday. So I wasted the entire day, starved, exhausted.

Cons: Proper connection time. I lost the entire day, and now have to get a cab for $100 instead of my colleague meeting me. 3 am is impossible. And I am still not in Tel Aviv.

Cons: The flight attendants were quick with the pick up of drinks. I had only been served my drink for five minutes and they were already coming around to pick up trash.

Good 7.6

Pros: Crew was good. As always not enough leg room if you are taller. Resent having to pay extra for more leg room.

Good 7.2

Pros: There was more legroom, seats were more comfortable, staff friendly

Cons: Better access to terminal, transfer from London plane to Chicago plane was cumbersome with lots of steps. We had a layover of an hour and a half or so and were required to stand in line to board next flight. My husband and I are older travelers and we look forward to having a few minutes to sit.

Mediocre 2.0

Cons: My flight to Reykjavík was delayed, which I learned of the morning of the flight. I realized that this would cause me to miss my connecting flight and that if I missed the connection I’d be stuck there for another day. I booked a very expensive nonstop with Delta instead of risking that.

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