Delta Aviation Demise
 

Friends and family bought me an 'experience' flight in a Piper Cub for my 50th birthday.

However, it appears that Delta Aviation, the company from which voucher was purchased, has gone bust and the voucher is now worthless.

Hopefully, the purchaser will get their money back, eventually, from the credit card company.

Anybody know where I can make alternative arrangements?

They didn't have a cub on their fleet. Did you know where you were going to fly from? the answer of the company that would have taken you up would be there.

I googled this for you which has more information than you posted, in case others have a similar problem: Delta Aviation Ventures Ltd
I hope you get your flight!

Clacton Aero Club have a Super Cub and are jolly nice people to deal with.
I did my tailwheel conversion there.
Good luck with it all.
