I've just returned from my first experience of "one class" flying, and I greatly enjoyed it.
Flying from MCO to MKE usually involves a change of plane - often at the dreaded DTW. (DTW Rule One: All pax changing planes must have at least one-quarter mile distance between arrival and departure gates.)
This time I opted to spend a little more and fly non-stop to MKE. Wide leather seats, real china and metal utensils, cloth napkins, complementary wine (even though I don't drink, appreciated by my parents when they fly MCO to MKE).
The people sitting next to me agreed - there is something about the clink of metal utensils on china that makes it seem more like a restaurant meal. And I was very pleased that on both flights a member of the cabin crew arrived at my seat with a smile and a questioning look on their face . . . and before they even asked the question I said, "Yes, I ordered a vegetarian meal". : )
I've had airlines screw this up or - more likely - some inconsiderate $%#^@ who forgot to order their own vegetarian meal *took* mine!!!
And we also agreed that we like the "one class" plane.
It was the opposite of being a tinned sardine when I had to fly from MCO to Tallahassee every week in the late 80s on a shuttle flight. I'm 5'9-1/4" and 135 lbs and I could barely fit in those seats!!!
Just a hassle free, pleasant journey. I should post separately about some of my security and carry-on experiences . . .
