Air New Zealand plane was newer and crew was helpful and gracious. Connection to Glasgow was a disaster mostly caused by our airline changing to British Airways to Glasgow. Because our LAX yo LHR flight arrived a bit late, we missed our flight to GLA and had to wait nine hours to get seats on another flight from LHR to GLA. No accomodations were made for us. We had to manage nine hours in LHR with a 4 year-old -- we had no other choice.

Will never again fly Air New Zealand from LAX to GLA -- an annual route for us as we have family in Scotland.

I haven't traveled internationally in 6 years and this was my first time with my 'newly' discovered gluten allergy. As a result, it didn't even occur to me to request a special meal prior to my flight.

The staff was kind and friendly (which always is the case with Lufthansa!). I felt like more than just a passenger but as a cared for customer.

The premium economy seats, while more spacious, were not much more comfortable. They reclined to the point that it was awkward when using the leg rest. Would be better if the leg rest could raise a little higher..

Right before boarding I checked to see about purchasing an upgrade to business for my Wife and I because she was not feeling well and the added room would help. The Rude desk clerk didn’t even check and just spit out no upgrades. Yet once on the plane there were several empty business class seats and they stayed empty the entire flight.

I thought our male flight attendant was not only slow to offer water, pick up trash, or respond to attendant calls, but he was also rude about it, making excuses when asked about the delays instead of simply apologizing and making sure to do better the next time. Also, the calzone breakfast was pretty bad. But other than that, the flight to LAX was ok. The entertainment system, as usual, was excellent, and we had room enough to stretch out during the long flight.

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,
