I am reviving this thread as I can't find any available seat for upgrade to business class (in advance of check-in) from EU to East Asia for 2026 using Qcredits. I would like to hear from you any advice you may have on how to search for U class / available seats in business class (non flexi). I come up with the impression that expert flyer does not include U class. Using the award flight finder of qatarairways.com is also very cumbersome.

Do you have any advice for me?

Yes, I understand that the most traditional way to use Qcredits is to upgrade at checkin at the airport but I would like to know if there are other possibilities to use my current 100 Qcredits...

Thanks!
