This ~week is my first time looking to upgrade from cheap economy ticket to business via the bidding for LAX-ZRH on 3/3. 4 days ago (2/19), the cheapest USD bid option was $980. To my surprise, today it's $1100. I should have realized there would be dynamic pricing, but hadn't thought about it. I also didn't notice anyone else posting about changing prices either. So, A) public service announcement to all the newbies out there! and B) Does anyone have info on how much prices change and if they move up and down a lot? Thanks!
