I know this type of question comes up a lot but what’s the best way to get BAEC Silver benefits on a Vueling booking direct with vueling and VY codes. Are there any benefits? I tried to book through BA but I imagine the route (below) isn’t offered on BA.com as direct flight. Also as a rewards flight but no luck on BA.com

So we’re trying get from AGP to BCN in Y basic fares. We are looking at Vueling but only if the Silver can benefit us, date is 2nd Nov. We need to connect at BCN for a BCN - MAD - JFK. Luggage (mostly) and seat selection are the main benefits we’d like. To avoid extra costs.

Any suggestions?

Thanks all. Safe travels.
