My first flight ever was in 1977 or 1978, MSP to LAX, on Western Airlines, the ohhhhhnly way to fly. Remember this little birdlike guy who rode on the wing? I'm pretty sure we didn't get pizza though.
We also flew Braniff somewhere before they went under, and I loved their colorful planes.
And my hometown airline was Northwest, which is now Delta, but at the time was Northwest Orient! (GONG!) AIIIIIIR-LINES!
Which dead airlines do you remember?
