Discount the published fare gap, layer in elite perks, and assign a comfort value per hour so you can see whether your upgrade bid delivers surplus value versus buying the higher fare outright.

Enter the cash bid you plan to submit for the upgrade auction.
Calculate the price gap between economy and the target premium cabin for the same flight.
Use gate-to-gate block time to value sleep and productivity gains realistically.
Estimate the extra value from mileage accrual, lounge access, or waived fees tied to your status tier.
Defaults to 40% to approximate the portion of the fare difference you truly value.
Defaults to $35 per hour to capture rest, sleep, and productivity gains.

Upgrade auctions vary by airline and fare class. Confirm bid terms, refund rules, and upgrade inventory before submitting payment.

Examples

  • Bid $320, fare gap $1,450, flight 11 h, status 30%, value realisation 30% ⇒ Valuing 30.00% of the $1,450.00 gap gives $435.00, status perks add $130.50, and comfort worth $35.00/hr adds $385.00. Total value hits $950.50, leaving $630.50 net on a $320.00 bid (197.03% ROI), so the bid creates strong surplus value.
  • Bid $210, fare gap $780, flight 4.5 h, status 0%, comfort $25/hr ⇒ Taking 40.00% of the $780.00 gap yields $312.00, no status value is added, and comfort at $25.00/hr contributes $112.50. The upgrade is worth $424.50, leaving $214.50 net on a $210.00 bid (102.14% ROI), so the bid still clears your value threshold.

FAQ

How do I pick the value realisation percentage?

Start at 40% for long-haul business class—lower it if the premium seat adds little utility, or raise it if you would otherwise buy the higher fare when seats are scarce.

What if my bid is refundable?

Set the bid amount to $0 to simulate a risk-free offer. The ROI field switches to n/a while still reporting the net value versus the equivalent cash fare.

Can I include frequent-flyer miles earned?

Yes. Add the dollar value of incremental miles to the cash fare gap or increase the status multiplier to reflect loyalty uplift.

Additional Information

  • Value realisation discounts the cash fare gap to reflect how much utility you personally derive from the premium seat.
  • Elite status multiplier boosts the realised cash value to capture extra mileage accrual, lounge access, or waived fees tied to your tier.
  • Comfort value per hour translates lie-flat rest, workspace quality, and post-arrival freshness into a dollar assumption you can tune for each trip.
