Nobody called United as United has not issued the ticket nor are there any United operated segments. The travel agency that issued the ticket refused to do any changes for fear of the ticket getting messed up and them being held accountable.
I spoke to ANA today and they explained that the business class seat of my wife got auto cancelled since the passenger was holding 2 confirmed reservations on the same flight. My case is the same where my PNR shows I am confirmed in both PE and business. ANA has asked me to ask the travel agency to cancel my booking in PE. The agency has again refused to touch the ticket unless ANA asks them in writing to do so.
Confused now about what to do since don’t want my business class upgrades to auto cancel. Am confirmed on 2 sectors and waitlisted on balance 2 sectors all using PPs
