UK based Neil wrote in to the Beetle warning travellers about Garuda. This is what he says:

Garuda have a reputation for being unreliable. On a recent trip to Indonesia and East Timor I had first hand experience of this. At check-in at Heathrow I found I was not on either the flight to KL or the onward flight to Bali. All my tickets were confirmed. The supervisor said this was common, and promptly found me a seat on both (Malaysian were the carrier in association with Garuda and Virgin).

In Bali, three days before I was due to fly, I found that I was not on the flights (flying with Merpati Nusantara) to and from East Timor. These had been booked through Garuda (by Trailfinders) in London. After phoning Trailfinders from Bali, the flights were re-booked, but had to be paid for again in Bali, a considerable inconvenience.

The moral of the story is never assume that that you have confirmed seats on flights booked with, or through, Garuda. Reconfirm at least three days before departure.
