Hi there- first post, so apologies if this isn't the right forum. But I could use some advise from some seasoned travelers.

I just booked a flight on Delta. The only seats remaining are the Delta Comfort seats, where they will charge me an extra $59 for the seat.

So I have not selected a seat assignment. However, these are the last two seats that are shown.

So if I don't select a seat, will one of those seats automatically be given to me? Without having to pay? OR...if I don't select the seat before hand, am I at risk for being bumped from the flight in the event it is oversold?

Any help is appreciated. Flight is on Sunday, today is late Friday night so any quick answers are appreciated! Thank you!!!
