My Yay!s (+) and Nay!s (-)
Airline Program (United 1K):
+ Priority on the standby list
+ Better/more help when I need it (than I think the average passenger gets)
+ United Club Access on International Travel
+ Priority boarding...along with all the credit card holders (boo)
- Priority baggage and free baggage: I never ever check a bag.
- Drink vouchers
- GPUs and RPUs: Company policy prohibits me from sitting anywhere other than economy during business travel. Personal travel, I never fly StarAlliance (or any other airline alliance), so I can't use them then either. Year after year, unused.
+/- Mileage multiplier: My miles go to my company, so good for them.
Hotel Programs (general):
+ Late checkout: can be really useful.
- Suite upgrades: I don't happen to like suites. (Long story there.)
- Breakfast: I'm strict vegetarian, so breakfast is seldom anything but melon and dry cereal.
