I have had the pleasure of flying Thai now a few of times on medium and short haul in economy and have found it always a pleasure.

The staff at check in and on the plane are charming, polite and always have tried to do everything to help. Add to the fact that ( and I know I am being sexist here so apologies ) they have the best looking stewardesses and one of the nicest sounding languages I am just a sucker in their hands.

All levity aside, the airline does have one of the newest fleets in Asia ( Airbus A310s, 320s etc ) and maintenance is generally of a high standard so safety is not normally an issue.

Routes are widespread within Asia as you can imagine and to major cities in Europe and America. The airline is also part of the Star Alliance with British Midland, Lufthansa and others so frequent flyer miles can soon mount.

The last trip I had was a short hop from Kuala Lumpur to Bangkok. Even in economy there was more than average room between seats so even a 6 footer should not feel cramped. On boarding there are always free English language newspapers ( including the ubiquitous International Herald Tribune ) to take and read during the flight. The food is usually an option of Asian and western food so all but the most picky eaters will be able to take something.
Most medium to short hop aircraft do not yet have personal LCD screens so at the moment its back to the past of peering round somebodys head to see the movie.

Of course its main base is at Bangkoks Don Muang airport. The airport itself is only average I would have to say in terms of services and facilities.

One drawback certainly flying from the west to Thailand is that they tend not to be the cheapest option unless you are lucky enough to get a special offer. When in Asia all the airline prices are pretty much fixed so there is very little difference between them all, so if you get the chance, fly with the airline of smiles.
