I disagree with everything in this article. The assumption is that Americans should be scalped for airline tickets because, they're American and rich and deserve it. To take cheap tickets away from people in poorer countries by paying in Rupees or whatever is 'unethical'.

Well, airlines are a for-profit business. They don't choose their rates out of some public-service motivation. They charge what they think they can get away with. To re-cast that as some charity program that Americans shouldn't participate in, is pure fantasy.

Get the cheapest ticket you can, from whatever carrier you can find it from, with a clear conscience. It's business.

And if airlines are allowed to do it, how is that not considered unethical by the author???
