Given an offer of 51,000JPY (about 378USD) to upgrade Y to PE on SQ12 from NRT to LAX on 20 June. As it was originally a saver mileage award booking I felt it was a good value and took it. It’s now booked in P class - wondering if I’ll now earn miles for the flight 🤔 Not really expecting any but I’m just pleasantly surprised that SQ allows paid upgrades to mileage bookings 👍🏻
