Virgin Australia UpgradeMe pricing and success

[bbtlife]

My recent PER – MEL return both unsuccessful at $135 (minimum bid +$10) . When I first bid I did think $125 was a bit low for east-west; minimum bids typically start much higher. Does the minimum bid change closer to the flight?

Another interesting PER - MEL bid success, following on from my last message on minimum bids changing:

• After purchasing flight, min bid was $125 so I bid $140 (min + $15)
• At ~T-36, I went to alter my bid just to check and now the minimum bid was my bid of $140. 5/8 J seats available at this time
• Just for some extra peace of mind I upped this by $10 to $150
• At ~T-24 (usually just after the first tranche of upgrades are offered) 2/8 J remained available
• Upgraded at T-13
