United Campaign: Enforce carry-on limits, reduce complaints and crowding

I hope this effort is a real and continuing one and that other companies follow.  Carrying everything onto the plane, to my way of thinking, is like any trend where if enough people say it's a good idea, even when it's not, hoards fall right into step, like lemmings.  

If I was offered valet service for a nominal fee to have someone carry my suitcase for me and I wouldn't have to touch it from the time I arrived at the airport until the time I was leaving at my destination, I'd jump at the chance.  That's how I think about letting the airline handle my bag.  So, even though it's well within carry-on limits, I check it and I'm glad I can.  My bag hasn't been lost since the 60's, or delayed for decades, those days are almost entirely over.  Maybe the next phase of retraining the flying public will be to board by carry-on size, smallest first.
