Hi, I am trying to book Vueling flights using BA Avios and noticed that neither BAEC nor Aer Lingus Avios show Vueling flights.
Vueling flights show up on IB, however, I am unable to update the address on my IB profile (which needs to match my address on BAEC) as I get the following error: S

"Sorry, an error occurred while loading this page. Please refresh it."

(also, the address line on IB does not allow dash ("-"), and I am not sure what needs to be in "Flat / letter" and "Additional information")

Anyone have any workaround?
