Although scattered light rain, no seemingly unusual weather at EWR. No special reward once on the flight to make up for that delay (I.e. still charged for snacks and alcoholic drinks). Delay was very frustrating. Also, not a fan of selections on United WiFi entertainment - very limited.

Excellent 8.8

Pros: Because the flight wasn't full we passengers in the main cabin had the chance to spread out a bit more, which was great on such a long flight. Also the flight attendant let me have my scotch for free! Hooray!

Cons: Without power at each seat it's difficult to take advantage of the otherwise free entertainment that is only accessible through the app or on a laptop. There was a DC power outlet at my seat (not all of the seats in the main cabin even have that) but guess what--it required a cigarette-lighter-style adapter to plug in. I certainly don't travel around with one of those! And most of the other seats in the main cabin had no access to power at all. My battery wouldn't possibly last through a 7-hour-plus flight without supplementary power. Oh well, fortunately there are still books and magazines. Just like old times. Be more like United or any other international airline, American!

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.
