This would have to be a very rare situation. I was a flight attendant for 5 years and never came across this. Also rather odd since for so many years a bag if peanuts was the snack of choice for most airlines.
In the past 10 years, I have had 5 flights that had FAs asking passengers not to open peanut products due to severe allergies onboard that flight. I fly probably just twice a year, sometimes three times a year.
Yes you can take them and eat them.
Eating peanut butter does not bother a peanut allergy person altho they will try to tell you otherwise. But peanut protein has to be in the air for it to be a risk and there is no peanut protein released form peanut butter.
They also can ask you not to eat but they can't force you not to eat them.
Peanut dust can be in the air, which could set off an allergic reaction. And, worse yet?? An allergic child sits in a seat recently vacated by a very messy child...a child that had had peanut butter crackers or sandwich. Now, there is peanut residue on the seat, arms and possibly tray. Yes, the vast majority of parents of these kids will ask to board early in order to do a proper cleaning and sometimes even spread out a sheet over the area.
Perhaps it's a new thing (well, new since I flew - over twenty years ago).
Still, all those flights and never an issue with anyone reacting to the peanut bags that were handed out to everyone. I guess I would honor the request, but I think it's a bit silly.
Well, 20 years ago we didn't see peanut free tables or classrooms in schools either. But they sure do exist today!!!
Can someone please explain this logic?
It's the whole 3-1-1 issue. If a substance will not hold it's shape when removed from it's container, it has to be in a 3oz, or smaller, container and be put into your quart sized baggie if you are using carryon baggage. And peanut butter and jelly most certainly do not hold their shape outside their jars.
But in a sandwich is fine since there really isn't close to 3oz of it.
As I said, I flew for the airlines for 5 years. Never ever ever had any issue with anyone reacting to the peanuts we handed out or any peanut product anyone had brought on board. As has been said by PPs, there are sill airlines handing out peanuts today. As far as someone smearing some peanut grease on the seat and then another person's child putting their hand on it and then to their mouth..well...that could happen with someone on a previous flight when there was no peanut alert. So, yes, i think it's kind of silly because i don't think there's a genuine risk. As i also said, i would respect he request anyway.
If you can show me one documented case of a peanut reaction from someone on an airplane, i will change my mind.
Have you seen someone go into anaphylactic shock?? I have. It isn't pretty. I watched my dd's best friend almost die from a food allergy last May. So, yes, it is a genuine risk.
I am sorry, but if my child had such a severe peanut allergy, I would not endanger their life by exposing them to so many people, such as on public transportation. I would certainly not expect or ask a plane full of total strangers to refrain from eating peanut products just for my child. Whatever happened to the days of inconveniencing yourself before you would ever ask others to be inconvienced??
And exactly how do you think these families are going to travel??? They have to use a car because so many people refuse to give up their peanut butter for a few hours on a plane???? Seriously??
Here's the thing. My dd, now 18, has always been what we call a 'discriminating' eater. Yeah, that is our nice way of saying picky, picky, picky!!! Her diet consisted of...peanut butter sandwiches (creamy only please), milk/dairy, mac and cheese, pasta and butter/parm cheese, cheeseburgers/hot dogs. And some veggies and fruits.
So, it was easy to just pack her a peanut butter sandwich when flying. But, after that first request to not use peanut products, we stopped doing it. There are other things you can bring to eat. You can actually sit at the gate and eat your sandwich there if you have to. Bring a baggie full of frozen veggies and add some grapes or cheese. Or some other kind of fruit. There are ways around this.
To the OP...can you bring a pb/j sandwich through security? Yes, you can. And in all likelihood, you won't be asked to not eat it on the plane. But, it could happen.
