I would say to go on the flight but be prepared just in case. Have an epi pen with you, Benadryl, whatever you need to recover when the reaction hits. You could even wear a mask if the people around you are eating peanuts. For me i would go ahead with your trip and not let the possibilities stop you from living your life as you want.
You haven’t bought eBay replacement headlights before then! I have never been able to get them adjusted properly to the point where they match even close to the factory pattern. I usually end up pointing them away to low just to be kind to anyone in front of them. The only saving grace is a love in the city and want didn’t need to rely on them for proper lighting.
