In the late 70s, Pan Am also operated a mini-hub in Guatemala City - a couple of 707s and one 747 inbound from MIA, JFK, IAD, and LAX proceeded on to SJO, SAL and other points in Central America. Connected through there a few times myself. Once I was on a 747 from SJO to GUA (was headed to MIA). We couldn't land at GUA (happened a lot during rainy season - kind of scary with all the volcanoes around GUA) - our 747 ended up landing in Merida to refuel. They then took all of us on to LAX (where the 747 was headed), put us up in a hotel (quite a party there at PA's expense!), and sent us on to MIA the next day. Pan Am - gone but not forgotten! Thanks for the memories!
