When I arrived at the airport for my Manila to Puerto Princesa flight, the staff at the check-in counter told me that the only seat left was on the Emergency Exit. I happily said yes. Why happy? It’s the seats with the best legroom.
If you’re as tall as me you’ll understand what I mean.
No more knees hitting the seat in front of me. No more standing up when someone nearer the window wanted some private time in the lavatory (Comfort Room). Plus you get to have a small chitchat time with the pretty flight attendant when she’s explaining what you need to do.
