What A Way to Run An Airline

I received an e-mail from Hawaiian Airlines inviting me to check-in online for my flight.  I attempted to do so and got an error message that said “special assistance is required, please check in at the Hawaiian Airlines airport ticket counter.”  When I called to ask why “special assistance” was required, they said it because I was flying to Pago Pago and couldn’t check-in online.  So why did they send me an e-mail inviting me to check-in online, thereby wasting my time when I attempted to do so?  Did they not know I was flying to Pago Pago?  Indeed it shows Pago Pago as my destination on the very e-mail that told me I could check in-online.  Another example of corporate stupidity.
