The food is always bad, and they didn’t allow use of electronics (phones, and they didn’t like me using my iPod I suppose because it looks like a phone?) on a 6 hr international flight when there was NO individual entertainment and no screens. What’s worse is I went into the bathroom right after a flight attendant and there was urine all over the seat! She either did it and left it, or she saw it and hovered over it, leaving it for the next person. Not classy.

Once the aircraft left the gate and started taxiing, it did the job. The crew also did their jobs. Nothing remarkable. Passengers were few, so everyone could relax better.

One day in advance, an e-mail announced that the flight would be delayed by 1 h 10 mn. Once at the airport, the delay was increased. by 35 minutes. Yet, at the airport and on the aircraft, the only explanation given was the overplayed refrain "Due to late arrival of the aircraft..." PLEASE, stop kidding us. Bad management is not the same as "late arrival". At 3 AM everybody was on board. No other arriving or departing aircraft in that CGK airport at that ungodly time. The pilot mumbled something about loading cargo. We sat an extra 50 minutes before taking off. This airplane has no screen of any kind in Economy. There were posters and a booklet describing the possibilities of entertainment. Again, who is kidding whom? Before going bankrupt, the old Philippines Air Lines used the acronym P.A.L. And everyone read: "Planes Always Late". The acronym is gone, but the delays are back, for sure. I am sorry that I did not go on a low cost 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.
