Cons: The outbound flight still had the exact same movie selection as the inbound flight had, even though they were six weeks apart for my trip. I really feel like the movie selection should be changed every month (or even more frequently than that), as I ran out of films to watch.

Also even when you buy a business class ticket British Airways makes you pay to reserve a seat in advance if you don’t have status with them. That feels over the top for a premium customer.

Pros: Amazing crew. Took care of people in every possible way and were concerned about their comfort. The food and drinks were above and beyond. Other airline CEO’s should fly Lufthansa and find out what they need to do to impress their customers. side pockets beneath the windows are great to have.

Cons: The only thing I can say is the seating on a long flight needs a little more room. When the person in front lets their seat back it gets to be a little cramped.

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

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.
