Useful list of things to say when asked to switch seats
This is a true story. We were on a full flight going to the Inauguration and a group of teenagers were on board with their chaperones. The kids weren't in assigned seats, so there was confusion when the kids were in other passengers seats. The kids found their boarding passes and all was well until a black couple with exit row tickets came in and wanted their seats. Two chaperones had wrongly taken the exit row seats, and the stewardess asked the couple if they minded moving to the back of the plane! It reminded me of Rosa Parks.
The couple were cool and said, "but these are our seats" and the chaperones moved to the back of the plane. They were polite, but stood their ground. It's a new day.
