I had a similar experience on a US Airways flight last December. The Kindle Fire browser allows the user to choose whether to optimise for mobile or desktop, and this resulted in two different prices. In relation to the legal questions raised elsewhere on this thread, I'm guessing that it's a non-issue when it's a built-in feature of the device. I think the argument could be logically extended to using plug-ins that switch user agent strings?
