As a ULCC Spirit guy is usually one of the two encounters:
“Spirit, you guys sure are growing fast over there. Nice to get on early”
Or
“Spirit, well don’t worry, we won’t charge you for your carry on(chuckle chuckle)”
I had a lead DAL FA tell me (I was offline DH in uniform on Delta) “I guess you can ride, but maybe I’ll charge you for your bags like you guys do”
Being that I was a paying customer I took the opportunity to remind her “you do realize this very flight is charging passengers a premium of $45 to sit in a middle seat simply because it’s closer to the front (not economy comfort)”
Just a reminder that pilots don’t create the pricing structure of their airlines.
