Reply To: Book outbound add return at a later date

[JDB]

Yes to A) and C) but definitely not B). Vouchers, whether they be Amex 241 or Barclays ‘upgrade’ are also governed by the BAEC/Avios terms so that once you have reached 24hrs before the outbound, the voucher is ‘used’ / unavailable for use, even if you haven’t used it to the extent permissible prior to that point – e.g. if just used one way when it could have been used for a return.
