I've been the Seattle Museum of Flight she's talking about and "the airliner from the 60's" she's talking about is probably the forward half of a USAir 737 that's in the museum. What she doesn't get is that even back then the 737 packed 3-3 seating across in economy, just like today, but only the front of the aircraft is in the museum so she probably sat in a first class seat. She can get even better service today but she has to again buy first class, just like she would have to 60 years ago.
