I'm looking at an Economy Basic fare ticketed by Iberia and operated by Finnair.
I am BA Silver.
Assuming I only need 1 bag checked is there any reason I would book the Economy Standard Fare rather than the Basic fare?
According to
https://www.finnair.com/go/2018.12-1...ch18_en_v2.pdf as it is operated by Finnair I get seat assignment and ticketed by Iberia so I get checked baggage. Is this correct?
