A while back i had bought a couple passes on eBay when I had a flight approaching. I ended up upgrading my flight so I didn’t need them after all. I held onto them for maybe 10 months and recently tried to use them. They were rejected. The club rep said that if the credit card that they were associated with got closed, that would invalidate the carp passes.
fortunately for me, I contacted the seller who was an upstanding individual and refunded me the full amount I paid. The passes were not expired and should have worked, but didn’t. The seller did the right thing and I’m grateful to them for that. In the future, I don’t think I’ll buy more off eBay. Just too risky.
