Someone recently asked the following question: I thought to myself, "Wow, that is expensive!" because in 2010, I'd redeemed miles to do: JFK-SFO-PVG-SFO-JFK in first class (F or XF) on United, and I paid "just" 145K miles (it would now cost 160K; 150K for C, so F redemption seems to have better value) in Standard Awards (not subject to blackout dates; i.e., if a seat is available, you can have it with miles rather than cash). This seems to me to be significantly less than this poster initially found out he would have to pay for a comparable TPAC trip redemption in business (C or XC) on DL. My entire trip was in XF, including the JFK <-> SFO segments, which were p.s. flights. It would thus seem that UA redemptions, at least for TPAC, might have more value than DL redemptions, but I do not wish to jump to conclusions. So, does anyone know the relative values of award mile redemptions among the major US airlines? Also, which alliance offers more value on redemptions?
