This whole companion thing is worse than I thought. Lots of people struggle to find fare classes to fit. I live in a smaller market so it’s even tougher. But here’s the supreme irritation. I can’t get a round trip with one stop in fare classes that are eligible for companion. But …. I can book a round trip to the first leg in T or U and a round trip for the second leg in T or U. So all four flights have a T or U fare available with sufficient layovers but if I try to book them as one round trip, they’re ineligible fare classes. I’m going to call and /or write Delta but this is just wrong. People getting their credit cards are being misled on the benefits.
