Mardee: appreciate the heads up.
On domestic flights, it gets you free booze (if they bother to do a service)
Ha! On a one hour late departing American flight (now leaving at 10 pm, DCA to MSP) in February I had a comfort seat and wanted my free beer (of course!). They announced right at the beginning of the 2-1/2 hour flight that they be skipping the bev service so people could sleep. I suspect so the attendants could gossip was the real reason. I tried to find the attendants in flight but failed, so rang the button and woke up the plane anyway.
Names assigned to seat classes are meaningless for comparison among airlines. There are just too many variables
So true, examples
Seat back monitors: included on all non-RJ Delta seats but not included in American domestic first class.
Liquor: Included all Delta fares transatlantic but for a fee with economy fares United or American.
Basic Economy Bags transatlantic: Delta includes one free bag, United doesn’t
Business Class: don’t expect lie flat seats unless the plane has 2 aisles.
It would be nice to have a chart cross referencing airline fare classes with free bag, voucherable fares or not, inches of pitch, cost of booze, etc. But recognizing that it also depends on the route and the model of plane as to what you get, it’s not just the airline.
