Twice last year I flew Air Canada Houston-Toronto-Zürich and back, and was very satisfied with the service both times.

This year flying Houston-Atlanta I picked Delta based on good memories from the distant past, and was not disappointed.

Me too. More space, better service — and I have a nice collection of various Swissair branded (stemless) "wine" glasses, because every time I asked about purchasing some, the attendants would wrap a few up and just give them to me.
