Thanks - I've correctly located both LEN & ABC, but I've disallowed BCN-ABC due to the fact it seems to be operated by Denim Air who aren't a OW affiliate.
Done, thanks.
Since both BCN-LEN and BCN-ABC are marketed by Iberia with an 8xxx flight numbers through their affiliate Air Nostrum, I think these would be allowed within a ONEWORLD ticket. LEN is Leon in north-central Spain and ABC is Albacete in south-eastern Spain. All Air Nostrum flights are ticketed as IB8XXX and Air Nostrum is an accepted OW affiliate. I think the Denim Air reference is to indicate it is operating the aircraft under a wet-lease agreement with Air Nostrum. Does that disqualify it? I believe I've earned AA miles on Air Nostrum flights such as this before so that leads me to believe these flights are eligible.
