Convinced my girlfriend to go to Cali for New Years on LX. She initially wanted to sleep on it (not an FT'er), but convinced her to book late last night, and 15 minutes after we received the tickets, the deal was gone.
At 660 EUR, we wouldn't have been able to get Y-tickets on those dates, so this is an amazing deal. And excited to be trying out LX's 77-product in J.
Fingers crossed that this will be honoured, but my guess (hope) is that because this was only alive for 2-3 hours, the 'damage' to various carriers was limited. So far everything looks fine, but I guess we will be wiser come CET regular business hours next week.
So a big thanks to OP for this.
