Just thought id pass on some useful info. Had helped a friend book MCO to JFk on DL T class (discount economy) and was offered the purchase of economy comfort for $29. You purchase the ticket then they offer you an extra, Which was the EC option. Airfare was a alittle over $100, so % wise it's near 30% more but for a 3 hr flight thought it was ok value . This means 10cm extra legroom and priority boarding. No food as its domestic.
