It's really a decent way to go. My Ex and I live about a 7 hour drive apart. before my son turned 5, I would have to leave work at 1:30pm, drive 220 miles (3.5 hours) and meet my ex. Then my son would come with me, and get a quick bite to eat and drive the 3.5 hours home. he'd be asleep in the car before we got home well after dark. I installed a video system in my car and he'd watch 2 1/2 full length animated movies during the ride.

Now, he hops a flight that's under an hour. He will fly in tonight at 8:30pm and fly back at 5:30pm. I almost get a full 48 hours with him and actually have the opportunity to do stuff with him on Sundays. We've done 1/2 days skiing or taken the boat out on Sundays with him flying. it's been a game changer. And the airfare is typically less than the combined gas spent previously by my Ex and I. and it's SOOOO much easier on him to fly an hour vs. being in a car for 7 hours.

Good job! I'm sure it'll be fine as they're older and it should be even easier.
