The crew was very rude, I was told I had to store my purse, the person next to me wouldn't store the carry on baggage, I needed to take scheduled medicine in flight, I couldn't as my purse was stowed. I was delayed for over and hour and a half after arriving. I had to stop and eat in the airport. With chronic health issues addressed this way I will probably not use United again.

Flight was on time and I received my checked baggage.

Seat was uncomfortable due to insufficient foot space. All (about 6) overhead bins in the rear of the aircraft were full because crew stored “essential equipment” in them. Crew was not professional. After takeoff they never came around to see if anyone needed anything and not even a glass of water was offered for the entire flight. They didn’t even ensure that everyone wore seatbelts on landing - woman next to me was stretched out hugging her companion while landing wilth unbuckled seatbelt. Entertainment screen did not wirk properly.

A mechanical issue meant our late night Sydney to Honolulu flight was cancelled. As a consequence, we were on the runway from 9:30 until 11:30 while they tried to fix the problem. Then we were at the airport until 1:00 am getting a hotel voucher and re-ticketed. Unfortunately, instead of having a day in Honolulu to deal with jet lag before going on to San Diego, we lost our Hilton reservation in Waikiki. We ended up getting a direct flight to LAX and on to San Diego. I will say the crew attempted to work with us. Daniel made an executive decision and got us on United. But no stopover in Hawaii.

Is nice a meal is included. I found flight fine over all I like you can pay just a bit extra for more leg room. I also found bathrooms a bit more spacious than usual planes.

Lots of interruptions of inflight entertainment. Hard to sleep when they have loads of announcements. General a pleasant experience. employees not very happy though or extend toward helpfulness. Am glad I did not need any extra help. Kinda felt that though about many employees I dealt with IN Hawaii itself. Maybe they just tired of tourists.

I guess San Francisco ATC (Air Traffic Control) decided the plane couldn’t leave San Fran until way past our take off time. Then it takes two plus hours to get the plane here unload and refuel and rest. So I missed my connecting flight to Redding. Which meant I had to fly to Sacramento. Then I had a pleasant 3 hour drive on I-5 (can you sense my sarcasm?!) didn’t reach my destination until 5 in the FREAKING morning. Around 8 HOURS LATE TO MY DESTINATION

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,
