i've taken both the lga-dfw at 6:05 am and 7:00 am many times (usually on a friday.) these have been rarely delayed, and there have never been long waits on the runway. as the day wears on, the delays can get really long; i was on a later flight from lga-dfw, with over 20 planes on the runways
lga has only two runways, and when there is bad weather, they reduce things to one runway, meaning that inbound and outbound are competing for it--big delays occur.
if weather is good, most incoming flights are listed as early.

I've also been doing almost the same Su/Mo DFW-LGA and Thu/Fri LGA-DFW off and on the past 6 months. I started doing the Friday morning 6:05am flight as it has always been on time compared to the Thu 9:25pm which is almost always delayed. I can stay at the Marriott LGA on Thurs night, wake up at 5am, catch the first 5:15am shuttle, and breeze through the elite security line at Concurse D to get to the gate by 5:35/40am.

Considering the 6:05am flight also gets in at 8:35am due to the time zone, its an added bonus that you haven't lost that much of the workday plus you can drive after rush-hour traffic.

I agree with seawolf. The increased frequency at LGA is a plus and offers one the advantage of arriving only 1-2 hours late rather than 3-4 hours late (or even the next day) because of limited JFK service.

I recently reported here my early AM flight to DFW was delayed 8 hours because the windscreen in front of the First Officer needed replacement. If I was at LGA, I would have had only a 2 hour delay.

When I fly domestic I fly out of LGA. (except for trancon flights) I live in upstate New York (Dutchess County) so I leave with a cushion of time. If there is no traffic I often snag a seat on an earlier flight. JFK has limited flights (except transcon) and the Van Wyck is always a gamble.

Of course when flying international its JFK. I find that even if there are delays in the NYC area often the international flights are still on time. Have to make those connections.

In addition to what everyone else said, I would also look at the type of plane you are going to be on. If I'm on an Super 80 then I'll pick LGA only because there are a lot of them in and out as well as there is usually a spare bird. If I'm on a 757, I'd prolly pick JFK as theres a greater chance of finding new metal if anything happens.

If your on a 757 mid day out of LGA and it goes out of service the flight is either going to be delayed a LONG time or be cancelled.

Newark is pretty much not good for anything. No offense to the EWR people, but when it comes to extra planes EWR has nothing.....

If arrival time is not an issue, I prefer JFK. Simply for the parking convenience and shuttle system. And of course you can fly anywhere on earth from there.
Since I book well in advance in most cases, I can still get the domestic upgrades, the majority of my flights.

LGA is always a crap shoot for parking, forget about it during "prime time".
And the terminal always maked me feel like I am in a third world country. The bathrooms? I wouldn't STAND on the bowl unless I had boots on. Only thing that makes it bearable is the AC and status. And the anticipation of one day actually landing in the outfield of Shea stadium, but alas, even that is going away.

As to EWR, I find the parking pretty poor there too. If I am flying in and taking a one way rental, then again, I defer to the shuttle which is pretty good.

I could have sworn this information was prominently available when you searched for flights to purchase on aa.com, but looks like they removed that. Unfortunate, but not surprised, that they aren't making the data as easy to find.
