I think this is right
I usually am flying economy class, but last year I flied first-class on a trip from Vermont to Texas. This is how it happened. When I arrived at the airport, the attendant told me the airline had been overbooked, which meant they were selling too many tickets for that flight. I was not in a hurry, so I offered to go on the next flight. Then I found out there was an extra seat after all—it was first class! As I sat in my first-class seat, I noticed the ride was much quieter and smoother than on other parts of the plane. When I buzzed the flight attendants, they arrived right away. Also, there were enough fleece blankets for everyone, so I was able to cover myself when the cabin got too cool. Because the seats were so large, I had lots of room to stretch my legs. Best of all, the first-class meal was really good. All of these pleasant surprises made the flight seem shorter than any other flight I have took before. Hope this helped as I changed some of the words :))
