DL's flights to JFK are sold as all-economy,with Gold-Medallion, etc getting preference to use upgraded seats. The 767 they use is still in domestic configuration, so they let their frequent fliers sit in the domestic first cabin! EI's premier cabin is in dire need of replacement. DL's cabin is far better, and CO's cabin is even better! AerLingus offer great service and their crew are fantastic, but they need to upgrade their interiors!!!!
