HNL
Mediocre 3.0

Pros: MU had been terrible on this trip. My flight MU544 was delayed from 00:55am to 12:10pm due to weather in Shanghai as they said. This made me miss my next flight to HNL. Next day i’m flying to LA and hotel they put me in in shanhgai was terrible :(

Cons: Could be honest about delay cause. Could put stranded passengers in better hotel rooms and not make strangers share a room. Could send bigger van so everyone and their luggages fit. (I have pics of packed van)

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

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don'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.

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.
