Got buy-up offer today.
Buy up to 75K for $999.
Had 72K AQM; 41 AQS; 19K AQD.
Was trying to quantify the value to me. There's some intangible value to eupgrades and higher standing on upgrade/standby lists, but the only quantifiable part is the extra 25% bonus miles. Assume I fly 72K again, that's an extra 18K miles or 5.5 cpm.
