This might be a pointless rant, since most of us have dealt with annoying seatmates, but this one stood out. On my Delta Air Lines flight from MSP to BOS in Comfort+, the passenger behind me spent most of the trip talking extremely loudly with friends nearby. It was disruptive not just for me, but for others sitting around us.
She also kept shouting to a friend seated in first class multiple times during the flight, and to top it off, ended the trip by making a speakerphone call. Overall, it made for a pretty frustrating experience.
That’s really all there is to it.
