Is there an advisable minimum time period to wait once an e-voucher is issued before trying to use it? I just received one and tried to use it immediately but on doing so, all three fields of my e-mail address, last name and e-voucher # give an error and advise me to re-check the voucher e-mail I received. Yet all are filled in 100% correctly
Best to wait a short while in case BA IT systems need to "catch-up"?
