If you are ever going to be stuck in an airport ....

... make sure it is Changi in Singapore.

Free internet access at desks to set up your laptop, charge batteries, phones etc; recliners in a rest area available even to plebs like me traveling economy; there's even a spa with jacuzzis and massage for goodness sake.

One day all airports will be like this.

[Update] I just had an excellent back and shoulders massage for S$17 (£6) - I might just stay here forever ....
