That bad? What do they do that's so annoying? So I don't do that to my kids when they are older and DD might actually be willing to do mother /daughter trips with me....
And then because he's nervous, it rubs off on my mom and makes her cranky as well. She got irritated for me going to the restroom as soon as we got off the plane. She was like, "You didn't tell us what you were doing!" Hmm...yeah I did Mom.
Then, instead of just going to the restroom right then, they all went when we got to bag claim. Meanwhile, I stood there and got all six suitcases off bag claim. And my Dad's response when he came back was, "Well, why aren't you moving the suitcases?" Um, because there's six suitcases, my backpack, and my carry on, and one of me? Also, how about the fact that tiny me just lifted a bunch of 40 pound suitcases off here without a thank you?
And then, although they do trust me and know I can handle myself in an airport when I'm alone, they somehow forget this when I'm with them and think I need reminders about stuff like taking off my shoes in security and where to put my carry on...and then my dad was like (before we got in line for security, this was when I decided to make an escape) "Take off your watch!" Well, you actually don't need to take off your jewlery or watch (or fitbit) in the new scanners. Which I had to tell him three times before he believed me.
Even my mom was getting on my nerves, and she and I usually get along quite well. But on a plane, she thinks I'm 12 and need to be told what to do. Er...no.
Basically, you should be fine as long as you're not a nervous traveller and don't nag.
