the geographically blind - living up to my standards

So Feeder and I were at the Subang Airport, checking in our luggage for a flight to the east coast (for open water diving course).

Me : I would like to check in our luggage.

Firefly ground staff : Flying to?

Me : (mind went blank for two seconds) ...

        (looked for the destination on the printed flight itinerary) ...

        (and failed to locate it) Kelantan...

Feeder : What? No, we're flying to Kuala Terengganu.

Me : (still reading the flight itinerary) ...

        (and found it) Oh yes!

Staff : ... (proceeded with check in procedure)

Me : (to Feeder) Are you sure we are flying to Kuala Terengganu?

        What if the hotel staff pick us up in Kota Bharu airport?

Feeder : I am sure.

Me : But last time we went to Lang Tengah, we took the boat from Kelantan.

Feeder : No, we didn't! We went to Terengganu!

In the end the hotel staff picked us up in the Kuala Terengganu airport. And we got our diving license.
