Mediocre 2.0

Pros: Nothing

Cons: Everything the customer service reps were very rude and condescending. United is awful I'm not sure how they are still in business. The rep refused to help me because she was getting off in 10 mins.

Excellent 8.0

Pros: More important than the trip home last Wednesday was the reason for the trip. We attended my granddaughter's wedding. Everything else was secondary. Even if the trip had been in a one wheeled barrow, it would have been good. To get to what you want which is the mechanics of the trip. The two people who attended to the aisle chair, most teams were competent. Some hadn't done many passengers so they were fumbling with the straps. I've learned that I almost alway have to ask for one at the gate where they check or issue, (what's it called, loading permits, some kind of pass, not landing pass. loading pass. I can't remember and my wife has gone to bed.) Well, they have to come up with an aisle chair because I've only got 1 1/2 legs. I always make it to the seat on the plane, but the competency of the various crews is uneen. Sorry my answer is so nonspecific but I don't remember one airline from another. Great people all, get the job done.

Cons: Not much I don't like. They get us there That is the main thing. Sometimes when the plane stops after it has pulled away from the Jet Way, the pilot gives an explanation that I find unfulfilling, not enough details. I suppose if they explained more, other fliers would find the explanation too verbose. I can live with it. Again this is about all flights and airlines. Nothing stands out, such as, " this awful thing happened when we left San Francisco."

Mediocre 2.0

Cons: We missed the whole vacation due to United flt. 599 being late into SFO. We missed the Zurich flight by 7 minutes due to a mechanical issue (overhead bin lid would not stay closed.) United customer service was very poor and after 16 hrs. at SO without resolution on flights and schedule, we just came back home. If Siss Air could have waited 10 minutes for 12 or more passengers, we would have been fine. I don't know if United communicated with them or not. This was a disaster!

Mediocre 2.3

Pros: The seats looked new.

Cons: United had us board and unboard and then board again due to flight delays. United also told us the delay would be only 40 minutes, but I looked at the delay in SFO and it was 2 hours. Eventually United also increased our delay by 30 minute intervals until it was about 2 hours. Once I arrivied in SFO I got a text message notification stating my luggage had been put on an incorrect flight and I would have to return to get my luggage. The attendants at the podium were rude. This was my first terrible flying experience ever.

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.
