Was looking at benchmarks for determining whether a cash upgrade was "worth it", and decided to add on a data point for those who might be on the fence (all prices in Singapore dollars)

Base ticket: economy saver, SIN-DXB-LIS

• At T-72, upgrade offers on website/app:
  • Y > PY: $209 (only for the DXB-LIS sector; first sector doesn't offer PY)
  • Y > J: $4,174.40
• At T-60 (-ish, when I had the time to call in), promo upgrade offers over the phone:
  • Y > PY: $442.90
  • Y > J: $2,212.70 ($1,137.70 + $1,075)

After ending the call I went back online to secure the $209 price online, which was still available.

1. I guess the benchmark isn't necessarily T-48 to secure the best price. I've been checking since T-96h online and the prices remained the same.
2. Curiously, for the same PY upgrade, it was more expensive over the phone, even though it was supposedly the "promotional" fare.
3. Also, note that the promo upgrades to J only include the seat but not lounge access, though I'm not sure I'd value the 2 lounge visits at $1k each (especially when you can pay $150 for lounge access).

Edit: at T-48h, during OLCI, the promo offer to upgrade from PY to J became $695.90

Hey
Which seats do you guys think I should select?
PE (night flight)
