I fly mostly sUA planes, but probably 30% sCO. I've noticed that, pretty consistently, the sUA flight attendant(s) in F are up and busy -- opening the galley, serving, etc. -- usually at 6,000 feet or so and always at the 10,000 foot double chime.

sCO cabin crews tend to sit much longer, often until the seatbelt sign goes off at cruise altitude.

Anyone else notice this? I prefer the sUA practice, as I get a drink faster in F and the sUA flight attendants appear busier and professional (i.e., not chatting in the jump seats). It doesn't appear there is a safety issue with the sUA F/As up at lower altitude, but what do I know.

Is this a difference in training? Culture? Because the sUA flight attendants are accustomed to thinner staffing and needing to work a bit harder? Or am I just off base in my basic observation?

Mods - I tried to find a thread where this fit -- but didn't. If I missed something, please move this post where it belongs. Thank you.
