Is a deadheading FA allowed to drink while flying?

i am curious because the flight this morning was so empty everybody got the upgrade and we still had 5 seats empty so an in uniform pilot and out of uniform (but wearing the ID cards) FA took two of the F seats. I just happened to notice her original seat was “FA JUMP SEAT” but during pre departure she asked for two bottle of liquor declaring quote “it was vacation time for her and she was heading to X Caribbean location”

i think the dead heading pilot was a little shocked making the “oh that’s funny joke” but I’m trying to give you a hint

on a different note wouldn’t you just put your work ID in your pocket so nobody would know?

Im not Gladys Kravitz so I’m not saying anything or writing delta about this or anything just more curious if it’s more bad form or against rules?

I believe the policy is different in-uniform versus out-of-uniform. If she’s out-of-uniform and headed out on vacation, I believe policy says it’s totally fine, as long as it’s not to excess of course.

Deadheading refers to movement of crew for operational purposes.

It seems like what you saw was a flight attendant simply using his or her flight benefits to go on vacation.

He or she was probably listed for the jumpseat to have priority in case the flight was full. I’m not sure how delta prioritizes non rev flight attendants for taking the jumpseat, but a lot of airlines do it on a first request basis.

Geez I posted an anonymous question. I didn’t post the flight number or anything and I don’t plan on sending this to DL so technically this could be hundreds of potential people nobody at DL is going to figure it out.

I asked because I was curious and as I didn’t know the answer asked people who also travel. Flyertalk really has gone down hill unfortunately.

You posted anonymous questions So that makes being a busybody OK?

Why does it matte? I think we know the answer. Time to let other people live their lives without your assistance

I got my answer please feel free to lock this

This makes some sense to me, as I would expect anyone in a DL crew uniform or anyone crew member who is deadheading to be able and willing to help in an emergency. If passengers ever see someone sitting in a FA jumpseat, they would similarly assume that the person is a crew member and perhaps turn to that person in an emergency.

Slightly off-topic, but related.
Years ago I was flying ATL-DCA on an evening flight. Sitting in 1A and next to me was a guy in a blue double-breasted uniform. We talked a bit and I asked if he was navy or public health - he was public health. The FA took his jacket and hung it. Then took orders for PDB. He ordered something alcoholic, a few minutes the FA came back and said she couldn’t serve him what he ordered.
After take off, she returned with the drink and an explanation and apology. She saw the double breasted blue jacket and thought he was a DL pilot. I guess she either looked at the jacket again or checked the manifest and saw he was USPHS.

No issue for me. Last year on an ATL-PBI flight I offered a DL FA not in uniform (had their credentials on neck and we chatted a bit so knew he was a FA) if they wanted a cocktail or wine. I had extra drink certs expiring and they took me up on the offer.
