查了一圈没看到答案，不知道是不是问题太白了，手下留情。暑假回国机票经济舱出票了，现在单独订可以看到PE超经美日段有票，提交upgrade说 Requests for upgrades cannot be made.
Upgrades are not available for the following.
- Tickets have not yet been issued
- The itinerary does not include a flight eligible for upgrade
- Check-in has been completed
- ANA CouchANA COUCHii reservations have been made for all flights
Other Terms of Use apply
是要电话么，或者到时候柜台问？
还有请问升过的分享具体需要多少里程么。订的时候可以看到来回差别是22k，单程是11k，但是升舱chart上说单程经济到超经20k，经济/超经升business是25k。
