Buying an airline ticket using Paypal

I had the opportunity to use Paypal to buy my Southwest Airlines ticket for next week.

The experience should be relatively painless if it wasn't for some quirks in the Southwest website.

But there is one quirk you should know about if you use Paypal. It doesn't like American Express. So you will not be able to complete the transaction if you ONLY have Amex as the connection in your Paypal account.

Now that both Northwest and Southwest are promoting the activity (spend $250+ and get a $50 credit) the other airlines should join in.

And where is Google Checkout in all of this? MIA?

Cheers
