Update: as of 10:30am EST – it appears that this deal is no longer available via United.com. It was a great run while it lasted!
Per this Flyertalk thread, you can get INCREDIBLE business and first class fares leaving the UK. For example, I booked me and 4 friends in BusinessFirst London-Newark this May for 293 Danish Kroner per person. These work only if you are leaving the UK, but you can book one-ways from London- US (or wherever else) at half the price.
To get these fares, go to united.com and set your country to Denmark in the top right. Search for UK cities to pretty much anywhere (think South America or Africa). I even purchased tickets on South African to Johannesburg (though they aren’t ticketed yet- most United flights will ticket right away). I even booked London- San Francisco- Sydney- Los Angeles- London over New Years for $1,500 US per person. Not quite the $100, but awesome, incredible deal! Lots of options.
I used my US Airways Mastercard (only thing I didn’t have already loaded in United.com) and put all details including my US address and then selected Denmark as the country and it worked like a charm.
Book quick, because this won’t last long! This is apparently available on other airlines as well, but I’ve only been able to get it booked on united.com.
