Aer Lingus Make us an offer upgrade- any success?

[Clara16]

just wondering if anyone has successfully upgraded an economy ticket with Aer Lingus new bidding system for business class seats. the lowest offer you can make is €380 one way, which also tells me is a very weak offer. my flight is May 29 to the usa

I have already purchased the economy ticket cost approx. €600 return

I've used this just checked my email and had offers of €560 and €580 accepted for flights to New York. I only used it twice was worth it imo
