Does the Barclaycard upgrade voucher work on Euroflyer flights?

[cheyes]

Hi,

I am trying to book a flight to palma in business using a Barclaycard upgrade voucher. When going through the process I get a response stating “Invalid” return flight. I think this may be because it is a BA EuroFlyer flight and wondered if anybody else had had this issue or alternatively knows that it should work?

Thanks.

Works fine as far as I can tell. I just did a dummy booking for two LGW flights using the voucher and got through to payment. If it persists, you may need to call.
