Just booked a one way flight for 35k spg points from tlv to NYC via heathrow on ba (with an extra leg to Miami a week later). My question now is that I wanted premium economy and that's not an option when booking on spgflights so I booked economy called ba they told me to call travel agent. Called spg they want $350 to change it. That's more than half value for the flight. Anyone have ideas on how I can get into premium economy on ba?
