I'm a United platinum traveling from the US to Singapore and am considering using the All Nippon Airways (Japan) code share to get ANA service but with my UA status and mileage/PQS accumulation on UA. Will I get UA PQS/PQM and also ability to select my seats before checkin? Trying to use my United status, get United credit but ANA service (versus flying actual United flights to Singapore, which were/are terrible).
