I flew on 10/23/98 PDX-AST, the ticket says AS, but I think it was harbor airlines operating on their behalf, plane was smaller than a SWM, flight number was 4557. Can anyone help me confirm the carrier, and aircraft type, Caravan? I have looked on departed flights, and now I'm stumped. Thanks in advance for any help.
