I must be the lucky one. From day 1 I did the Mia-Ord commute no problems. Always made first flight.

Lineholder in LGA currently no prolems commuting LGA-MIA or vice versa. And I do this commute on weekends at times flying in same day as well.

Things could always change, but at the moment its been mostly a breeze.

Don't let the commute thing scare you, if that's what your heart is set on doing do so.

I'd rather be living where I want commuting 90% of the time first class on a 2 hour flight than commuting for 2 hours by car stuck on the Cross Bronx. Just plan accordingly always and you should be good to go.
