My husband received a 15 mile helicopter flight as a Christmas gift. He registered the voucher on Boxing day. Shortly after registering it he had to undergo major surgery and was not able to take the flight for several months. In September he tried to book the flight, but could not remember his password, and the website did not recognise his email address to change the password. He has emailed the company 3 times and to date has not received a reply. When he telephoned them, they said 'We are Acorn, this is nothing to do with us, you have to do this through Virgin.' What a terrible waste of money.
