One interesting consideration in this discussion is that flights to and Orlando have so many more young children than on typical routes.
When I'm flying somewhere other than Orlando, there are usually a few young children, but not many -- perhaps just one or two. In the unlikely case that a young child is not assigned to sit next to a parent, the airline counter agent or gate agent should be able to reassign their seating from the seats that are under airport control (and were not available to anyone for pre-booking).
Compare that to Orlando flights. During periods when school is not in session, there are plenty of families with children of all ages. When school is in session, there are still plenty of families -- but now most of the children are babies, toddlers, or pre-school age kids. (Families of such young children have learned that WDW crowds are down and prices are lower if they travel when many other families have kids in school.) So you could have a flight with dozens of children under 5 or 6 years old!
Now consider that many of these families will choose to save the cost of "preferred" seats, choosing instead to rely on the seats that the airline assigns to them at 24 hours -- which may or may not be contiguous seats.
Not a good combination!
And that is the problem. If I have paid addtl to be seated next to my traveling companion, be it my young child, my dh or just a friend, I can't understand how anyone is going to expect me to change seats to enable a family to be seated together!! I did my homework, I paid extra for the seat I wanted. Not giving it up to someone who waited until the last minute or decided to not pay the extra.
And with so many families flying to Orlando, that is the one route that is more likely to happen. So I either book SW and board via boarding group, or I fly JB and pay for the seat I want.
I disagree. I feel it should be the AIRLINES responsibility to notify the passengers there's going to be a change and help the passengers find an alternative. Granted, that doesn't happen now, and yes, current flyers should check their reservations at least weekly.
I understand that ...and it used to be that way. BUT...it just doesn't seem to work that way. A few years ago, I arrived in WDW on Sunday. My dh and dd were arriving the following evening. My dh is obsessive about tracking flights, so was checking on their flights (with JB) all day...right up until the time they left for Logan...around noontime, for a 3pm flight. The flight, a connecting one, was ontime...gave the gate number. So, they get to Logan, 45 mins later, only to find that the flight had been cancelled!!! No notification via his cell phone, which he always lists when traveling. But, they were told that they would be put on a flight to NY about 6:15. Ah, that's going to make it difficult to make the 6pm connection there. And that flight was the last one out to MCO that night!!! So, they got rushed to the gate that was almost done boarding the 1:30 flight!!! They got onboard, the doors closed.
It would have been nice if they had been notified.
So now? I start checking on my flights weekly. Then, when I get to a month out, it's every 3 or 4 days. Two weeks out?? Every day. Yes, it's a pain, but at least I know I'll catch something if it changes.
Ordinary good customer service would include quietly rebooking the child or the parent to be back on the same plane as the other, upon request, even if the parent did not catch the cancellation right away. This might include forcible booking, which, incidentally, can always be done by pushing just the right buttons (keys).
But that's going to be an issue if the flights are full. I always check on my flights constantly. That way I can be proactive, rather than worry about someone else trying to fix it down the road.
