Sure. I'm 42. When I was in 8th grade I did the Washington DC trip, and flew from San Francisco. Airfare was $800 for each of us, booked as a group.
That was the early 80s. If the prices had gone along with inflation, what would that fare be now?
FWIW airlines can't always help with seating issues at the gate. DS and I flew on Saturday, and had 3 flights that day (low Miles-cost flight involved 3 flights just to get to Orange County in California). We were never assigned seats on the second flight, then that flight was cancelled anyway and we were put on a flight 2 hours later. When we were assigned seats, they were 5 rows away. The instant I realized that this could happen I started helping DS deal with the possibility if we couldn't switch. I asked at the gate about switching, but it was 100% full with people hoping to get on board (if we'd been more flexible I would have taken the $200 per person credit they were offering and not continued on that day!). So when I got on board I put my bags on my seat, took DS to his seat, got him settled, and made sure the FA knew we'd love to know if someone else would like to switch. I ended up making two deals (one with a guy who wanted to sit near the college women who were sitting near my seat, LOL, and the other with a woman who had been separated from her family and didn't mind switching for a kid younger than her daughter), and got one row away from DS.
The FA was happy we got closer, but couldn't help. He was actually too busy trying to get people to put their bags in properly (he was fabulously sarcastic, it was awesome and I thanked him at the end of the flight) and trying to keep people from just randomly switching seats *in hopes* that no one would show up and take it, so that was fine with me!
And in the end DS had a fabulous time on the flight and only checked in with me once (putting his hand through the space between the seats and saying hi), and now WANTS to sit separately from us in the future.
