The Webflyer blog mentions that United has a very inexpensive $639 fare from DC to Sydney Australia—just about the lowest I’ve seen from the east coast. The same blog also provides a bunch of discount codes for Amtrak (including discounts on Acela trains, which is quite rare). (Max, a co-worker, just pointed out that United has a $599 r/t from JFK to Sydney. Even better. Perhaps I should actually do some research before I post stuff…anyway, you can get it at United.com under their e-Savers.)
Incidentally, you know it’s a slow news morning when I’m posting train discounts.
