I did the reverse commute, NYC-DFW.
Getting on flights wasn’t an issue. There were normally so many options. SWA is pulling out of EWR so that will cut out that one.

Going to work be advised that EWR is about an hour from LGA/JFK. There is a private airport express bus that I think leaves once an hour between the airports. May be an option getting to work but not the greatest. Not like DAL/DFW.

The down side of the commute was the length. About 4 hours each way.
