On a recent flight I had a bulkhead seat so I was forced to put both of my carry-on itmes in overhead storage. The gentlemen sitting next to me boarded late. He removed my bag from the compartment over my head and moved it seven rows back. That bag was my handbag and it contained currency and medication. I put it above my head so I could get it quickly once the plane reached altitude and so I could keep my eyes on it during take-off and landing.
I objected to this gentleman moving my bag in such a presumptive fashion. He had a very large and very heavy bag that did consume all of one over-head storage bin. His response was that my bags were smaller and therefore easier to wedge into space further back in the plane.
I said nothing more, and when the plane reached altitude I went back to the storage bin and retrieved my bag. I do not, however, think it appropriate behavior on his part. He could have boarded the plane when I did and then he would have had more choices about where to put his luggage. I rather think that when you are the last to board you cannot move the luggage of another person. Am I incorrect?
