I have an upcoming flight on an A220 which I am super excited for (chose this plane over an A320). I have three questions that I have not been able to figure out an answer to. Any input is appreciated.

1. I understand that seats 16CDE offer extra leg room because of the limited recline of seats 15CDE (especially seat 16E because there is no seat in front). Is there any benefit to sitting in seats 16AB (16A shows up as preferred on Delta seat map)? I am currently in 13A but have the option to sit in 16A.

2. Further, 13A is not showing up on the Delta seat map as a preferred seat. Is there going to be an unwanted surprise in this seat that I am unaware of?

3. Is there a coat closet on this plane? On the Delta seat map no coat closet is showing up (for example the A320 does show a closet on the map).

Thanks!
