I flew first class on Delta last summer to Chicago. The entire plane looked a million years old, taped seats, broken tray table, horrible service, etc.
I connected to an SAS flight where I flew Regular Joe--felt like A+ first class after having been on Delta.
LOL...we recently flew United 1st class to NY. The plane was ancient.
The flight attendant had to jam a panel in the ceiling, near the coffee/drink area in front, to get an ‘80’s looking TV to drop down for the *greeting*/safety instruction video. That’s where the in-flight movie played, as well.
We figured that the flight attendants were likely in their prime about the same time that this aircraft was.
