I can't think of two things more opposite than...
FLYING ALONE and FLYING ALONE WITH YOUNG CHILDREN.
I have done the latter almost 60 times in the past 6 years and have experienced the full gamut of adventure...

...the GOOD: on time arrivals, happy babies, helpful passengers, new friends, gracious airline staff, business travelers who would offer to carry the stroller or go get my dinner so I didn't have to haul everything, first class upgrades with meals, cooperative children, fun trips, smooth layovers, in-flight naps...
...the BAD: lost luggage, my cell phones falling on the tarmac (long story!), broken strollers, missed flights, hours on the runway, nursing in the air, diaper blowouts, rude passengers, abrasive flight attendants, running full speed from A to C in Atlanta with a baby-stroller-backpack-2 bags for the last flight leaving in 10 min (more than once!), sleeping in airports, 2am arrivals, lightning storms in flight, full body searches of my 2yr old (through random selection) where I was forbidden to help or touch him in any way...
...and pretty much everything in between.
Just going through security with children by yourself is a feat.
Everything you own has to be taken apart, disassembled, and put through the machines, but the TSA folks cannot help. This baffles me. If I take the baby out of the car seat and have to put the seat, the carrier, and the stroller through x-ray- where does the baby go while I do this and take off everyone's shoes and coats? I have handed them to friendly strangers before or even put a blanket on the floor to lay them on. While all the TSA folks stand with their arms folded watching. Why is it they can touch your stroller after, but not before? I'm confused.
Anyway, this past weekend I had the opportunity to FLY ALONE. I printed my boarding pass at home, took my 2 carry-on bags, and walked to the gate to get on the plane. Are you kidding? Is this really how other people travel?! I actually napped on both legs of the trip. It
is possible to sleep on a plane. It's not the plane, it's my fellow seatmates that were making it impossible :) And the airports? No problem. I have always dreaded the regional jets because to get off the plane you have to go down narrow steps, through a tunnel, up steps, through another tunnel, and up more steps. Have you ever tried this with 2 kids, 3 bags, and a double stroller, by yourself? The gate agents won't help. And not only are the majority of fellow passengers unwilling to help they also are loudly annoyed at your misfortune and inconvenience to them. I've occasionally had a few pilots actually help out.
It was also interesting to me to see all the changes being made to security. This was my first experience with the full body scan machines. You enter a narrow booth, stand sideways, and strike a pose with your hands making a diamond shape above your head. Then a mysterious person behind a one-way glass wall inspects your naked scan. While this is happening you are standing on yellow footprints, nose-to-nose with TSA security waiting for the "wizard behind the glass" to tell them in their ear which body part to pat down. The lady in front of me had her chest selected. Oh my! And my fate? My head. Seriously?! Is there something I should know? What did you see in there? Totally bizarre.
It was a very smooth trip. As much as I missed my kids, it was a welcome break and I appreciated all the small, simple joys of taking to the friendly skies.
