Yes definately I can smell peanuts/peanut butter...to a fault.
The other day I was at work and was helping a co-worker with something, I had walked away to finish it up on a different computer that I needed. I started feeling the familiar tingle - my tongue actually started to itch and my eyes started running and I coughed quite a bit. I smelled peanut butter and crackers - like those cheese crackers with the pb in them... I turned around and there she was standing right behind me chewing. I asked her if that's what she was eating, and she said "yes, actually, why are you allergic?" I nodded and went and found my benedryl and inhaler and she apologized profusely as she didn't know...

I can smell if there is peanutbutter, peanut sauce or someone eating chocolate or peanuts talking to me. I don't know if my son would recognize the smell. They have it in his lunchroom.
I also one time confused pop corn at a concert with peanuts. It was driving me nuts. I try not to inhale it in too much.
At the mall they sell roasted peanuts. When you walk by in certain areas you can smell it.

The worst in on a flight. When they serve peanuts and you have to sit there smelling it and knowing everyone is touching everything in the plane after eating peanuts. It is a scary situation. I bring wet towels to wash my tray table and seats. I try to avoid touching knobs for air and lights. I bring all my own food to eat while flying.

Allergic to all soy, all nuts, peas, beans, sunflower. Started at age 40.

Nosoyforme, I fly often and never requested a peanut-free fliight on Southwest until last month. A friend with a PA child convinced me that I should - and said it was very easy.
It IS easy. I asked the agent at the gate - she gave me a paper to give to the flight attendant....and that was it. EASY! The flight attendants just served an alternate snack that they carry on board all the time anyway.
Sure beats sniffing and coughing for the entire flight.....no one glared at me and no one missed the peanuts.
