I got asked whether there was anything else in the bag last time, and I’ve heard of others being checked or searched and made to take stuff out, I’ve been walked to the weighing/x-ray machine to check I don’t lie about the weight before but never checked.
Are you taking another bag of checked in luggage? That might be the differentiation, if you’re just taking a bike bag and a small carry on for a week they might question it.
airports are near the top of the rule one zones, be nice be polite and smile.
I suspect a healthy degree of this. I managed to get on the next flight when mine was overbooked when the guy ahead of me was in the same situation but chose to go down the Ronnie ******* Pickering route and I’m guessing didn’t fly till the next day as a result.
