I was in SJO last weekend and sort of had an interesting situation on American Airlines. I booked my ticket to SJO on their website about 3 months ago. At the time of booking I selected my seats and that was that. Occasionally over the previous month I would checked on AA.com to see if I could improve my seating. It showed , on the change seats prompt, only about 3-4 available seats going to and coming from SJO. However on the day before the flight it showed about 30 seats available and I was able to improve my seating. The same scenario repeated itself on the return flight. Each way the flights were about 75% capacity even though the advance booking made it look like 95% or more of capacity .
Now I have read in some of your previous post that you are a financial guy not a travel guy. However, I have a feeling that you may have some close friends who are travel guys.

Is American Airlines playing games with their website seat selection to make the flights look booked to increase their fares or is it some other factors? Thanks in advance.
ps. If you see Speedy1 arounf town send him my regards.
