Great idea, but poor execution - at least for the customers. You can not choose the bid amount. The starting bid for me to upgrade from premium economy to business for a single segment was €900 per person! That's more than buying business class ticket to begin with. I suggest following to improve the app -allow to change bid amount - indicate steps. (I wasn't sure if I clicked "ready to bid", I will have another step to finalize or I was actually bidding. - allow to cancel the bid.

Your feedback matters to us as we prioritize enhancing user experience; so reach out to us directly for further assistance. Starting bids are determined by our airline partners and can increase based on auction activity. Our final confirmation screen and action button ensure users are aware they are joining an auction.

There was no inventory at the end of the auction, so we were all losers. So this begs the question, why was there even and auction. Ridiculous. It was my first time using it. Overall, it worked well until the end, and then in the last 4 minutes, it kept glitching, I would have to log back in each time and then hope the auction was still going, it also froze many times in the end. You need to make your platform more sturdy and reliable, and stable.

Hi, please note that availability isn't guaranteed in our auctions, as outlined in our app. We value your feedback and suggest reaching out directly to our Customer Service team, as we haven't received any communication from you. Your experience is unusual and might be related to the airport's internet connection, so please contact us directly!

Absolute garbage of an app. I learned about it from their agent who approached us while in line to a TAP Portugal flight. He asked if whether we would like to upgrade to Premium Economy for a pretty low price. We naturally said yes, only to find out it's a bidding process. We won the auction, only to get the notification "sorry, there are no seats available for your upgrade". Why even offer it for a bid if it's not available? Don't waste your time.

As clearly stated in our app, last minute upgrade availability changes throughout an auction and we cannot guarantee availability on any flight. This is one of the reasons we are able to offer a starting bid that is lower than the full fare or the price to upgrade at check-in. But there’s always a chance to win and there’s no cost to participate!
