I was surprised to discover a new United promotion in-app this week while I was reviewing upcoming trip details. A banner appeared with information about fall travel and the ability to earn up to 50,000 bonus miles on flights to Europe in economy:
Bonus miles are awarded at 5x the fare in addition your regular miles earned by status - meaning a 1K earning 11x miles will actually earn 16x miles for the flights. That's a nice bonus!
Curiously the only cities noted for this promotion are London, Amsterdam, and Paris - maybe there are low travel trends to those cities?
The promotion expires 12/13/23.
