A friend of mine once had a ticket from ORD-TUS (on HP I believe), but showed up to MDW. He eventually found a ticket on NW via MSP and was eight hours late arriving.

Edit:
The wrong-NZ flight was indeed in a Full House episode. A synopsis can be found at this link:

In addition, when said with a heavy Kiwi accent, 'Auckland' can sound like 'Oakland' to the untrained ear.
