All legs from AAA-BBB-CCC-DDD is on UA (W class).
I have enough miles to upgrade and willing to pay the co-pay, but how do I know prior to booking, there is availability in J for those legs for the upgrade? Is this searchable online or do I have to call in?
I don't want to be in a situation where I booked and paid for (W) and wanted to use my miles to upgrade but there is no availability (J)?
Please help.
1. Search using "expert mode" on united.com. "R" space is the upgrade fare class. If R>0 you can upgrade at booking. You should search segment by segment for the most accurate results. R may be available on some segments, but not others. If so, it will clear on those that are open and waitlist on those that are not.
2. I'm not sure why you're referring to W fare class. There is no requirement you book a W fare for a miles + co-pay upgrade. That is only a requirement for using a GPU on an international flight.
