I terrified of blue, too.....I mean yellow!!
Surreal....maybe you could depart MSY earlier to ease that connection? 30 minutes at ATL is tight...
Could you buy a front seat to put you at the early deplane position ?
The scenario of deplaning tight connections by request first rarely works, imhe. There are enough bad actors who think this the calling to just get off before their turn since no one will know.
I ONCE in my flight career had a pilot come on the intercom say, "after we land, seats 3B and 27 C are the only ones to get up, due to tight connections ".
That worked.
