Nice sale with Aer Lingus, Iberia, AA and British Airways from Chicago to London. This twist here is that the flights are sold as BA codeshares. Best prices seem to be a combo that includes Aer Lingus, when booking the codeshares seem to cause an issue on the BA website but do price out on Expedia.
