Thanks to Prospero for actually showing that seats are available now and then. I've called multiple times to BA over the past year with various requests for flights on EI and never had one or anything remotely close be available.

I'd just like to be able to get a hop across to the UK from DUB/SNN or vv for 10K BA as opposed to being socked for $300. BA has always had quite good domestic/short haul availability. It seems EI doesn't endorse the same theory.
