Slightly off-topic, but are the RTW award tickets the same for these three airlines?
Delta
miles required: 180K economy / 280K business
ticket: maximum of 6 stops, max of 3 stops per continent, no backtracking
United
Miles required: 180K economy / 260K business / 350K first (if available)
ticket: I can't find this
Max of 16 segments, 5 stops
American
Does American.offer a RTW ticket you can book with miles? I can't find it on their website
This Thread will give you all the info you need on AA RTW tickets
Miles required:
ticket: Max 16 segments & stopovers
AA RTW tickets are by far the best value. Basically, they're distance based and are limited to 16 segments. However, you can have a stopover at all 16 segments if you'd like. There are a few other restrictions & rules noted in the other thread.
