So a while ago PHL/CLT-DFW/DEN were listed as exceptions to the no meals sub-3.5 hour rule because of "business" market. Ok, we all know its because they are fortresses of much better airlines (AA and UA respectively). So here's my question, Expedia bills DFW-CLT as "breakfast" or "lunch" but DEN-CLT as "snack" (on all 3 flights). What's the difference in the new catering scheme? These are all for flights in July.
