Going a little further back, here's my mom as a kid standing at bottom of stairs getting ready to board UA's current inter-island partner (now Hawaiian Airlines).
For the geeks, I looked it up and it seems to be a Sikorsky S-38s or S-43S (probably the former as the one below is a S-43s and the windows look arranged differently). Timeframe would have been late 30s considering my mom's age at that time. Both were in service for Inter-Island at the time.
