She couldn't give me such a seat for free, but she suggested I check with the gate agent when I got to Philly. In the meantime, though, she saw that there was no one sitting next to me in my block of four seats between aisles, and I was on the aisle.
I didn't do any better after I got to Philly, but the seat next to me remained open. No surprise; no one's going to intentionally pick a single middle seat surrounded by other passengers.
I ended up watching "The Spy Who Dumped Me," which was outstanding, tried to get some sleep, and then watched "Mamma Mia: Here We Go Again" for the last couple of hours of the trip. We disembarked just as the movie was ending, but I doubt I missed much.
Unlike my recent flights, the food was pretty disappointing. The "Cajun chicken" and rice was a faintly spiced creamy chicken stew. Maybe I should've gone for the pasta with pesto.
