It is a shame that F on a 2-class plane is so inferior to C on a 3-class plane. I strongly concur that calling the front of any 2-class plane of which I am aware the "First Class cabin" is a gross mismoner ... and does violate "truth in adversizing".

And while on the subject of "TIA", I contend that if one has to change equipment in the course of getting from origin to final destination, it violates TIA to use a single flight number! Same flight number should ALWAYS mean same piece of metal (barring an unforseen mechanical issue).
