Pros: The crew was amazing and cheerful considering the 2 hour delay and that is was so early in the morning

Cons: The communication was non existent. We started to board then suddenly the crew shut the door and everyone disappeared for 2 hours. We were left wondering what was going on and there was no one to ask!!! No updates on the apps just that our flight was boarding at a time well past

Pros: The plane was timely and clean.

Cons: It’s suggested to arrive 2hours before your flight, however the check in desk wouldn’t allow anyone to check in and take luggage until 1 hour before the flight began boarding. Keep in mind we still needed to get through security. Was a little annoying but not to awful. The worst part was the seating

Pros: While biased since I was in First class, everything was enjoyable and as expected of a first class experience. The free Wi-Fi on this flight made it extra special- can’t wait until its standard on all flights!!

Cons: Only real complaint is that Delta doesn’t seem to restrict size of bags taken as carry on and the time wasted but some trying to squeeze their obviously oversized bags into overhead compartments is painful.

Okay 4.3

Cons: I choosed this very very expensive flight because it was so import to be home in CPH at 9.00 for an important meeting. My flight from Chicago was delayed and nothing was done by the pilots to arrive on time. Despite the delay, I managed to arrive on time to my Connecting flight to CPH - only to realize that I was moved to a later flight. Now I have spent 2.300 USD on a poor flight that do NOT bring me to my destination on time. I am a frequent flyer, and will do everything I can Avoiding United going forward. Never United again

Pros: The crew was fantastic. The seats were very comfortable and the entertainment screen functioned perfectly with a great selection of things to watch.

Cons: The boarding process seems slightly longer for delta than other airlines. I figure you’re aware of this and are working on streamlining this. Further while the safety animation yo have made is cute is a little confusing at times.

Pros: The crew on my flight it self did a great job but comfort is not there. I don’t think I’ll fly with Frontier anymore. It’s not worth the hassle.

Cons: The experience was aweful, simple language purchase took me two days to get. 1 days of stress figuring out how to buy my carry online. 45 min wait to talk to someone. The good thing was the call center representative was patient and help me out, if not for her I would’ve have to spend more than $650

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.
