Hi there. I was just charged $100 change fee when I upgraded from PE to business class for my upcoming trip. When I called back, the agent said that it was the booking fee for upgrading, over the phone. Is this the standard practice from CX?

My flights from LAX to TPE have been cancelled. I called in to confirm the changes. While I was on phone, I asked about the upgrade price (one way) and it was cheaper than I would’ve paid if I booked it online earlier. I went ahead with the upgrade over the phone. However, the agent never mentioned the $100 fee.
