Narrative:

As we leveled at cruise altitude departing denver for casper, wy, the flight attendant (relatively new) advised me that a heavy set passenger that boarded our flight had asked for a seat belt extender. (The flight attendant has one extender that she usually uses for passenger briefing demos.) she gave the gentleman her belt extender and proceeded with cabin duties to prepare for takeoff. As we approached departure runway, we were cleared for takeoff. The flight attendant had closed cockpit doors indicating her readiness for departure. It wasn't until cruise that our passenger had informed our flight attendant that the belt extender did not fit the aircraft belts (buckles were not compatible). I asked her to try a few suggestions, including he suck it in and fasten the belt somehow. He was either unwilling or unable to fasten belt for landing. I believe he could have informed flight attendant before our departure, but may have not wanted to draw attention to himself. It would, at the very least, have forced us back to gate to find a solution. I've talked to maintenance and longer belt straps will be installed in this newly developed aircraft.

Title: AN MLG ACR ACFT WAS OPERATED WHEN ONE PAX SEAT BELT DID NOT WORK SINCE HE WAS TOO LARGE FOR THE NORMAL BELT AND THE EXTENSION DID NOT WORK.

Narrative: AS WE LEVELED AT CRUISE ALT DEPARTING DENVER FOR CASPER, WY, THE FLT ATTENDANT (RELATIVELY NEW) ADVISED ME THAT A HVY SET PAX THAT BOARDED OUR FLT HAD ASKED FOR A SEAT BELT EXTENDER. (THE FLT ATTENDANT HAS ONE EXTENDER THAT SHE USUALLY USES FOR PAX BRIEFING DEMOS.) SHE GAVE THE GENTLEMAN HER BELT EXTENDER AND PROCEEDED WITH CABIN DUTIES TO PREPARE FOR TKOF. AS WE APCHED DEP RWY, WE WERE CLRED FOR TKOF. THE FLT ATTENDANT HAD CLOSED COCKPIT DOORS INDICATING HER READINESS FOR DEP. IT WASN'T UNTIL CRUISE THAT OUR PAX HAD INFORMED OUR FLT ATTENDANT THAT THE BELT EXTENDER DID NOT FIT THE ACFT BELTS (BUCKLES WERE NOT COMPATIBLE). I ASKED HER TO TRY A FEW SUGGESTIONS, INCLUDING HE SUCK IT IN AND FASTEN THE BELT SOMEHOW. HE WAS EITHER UNWILLING OR UNABLE TO FASTEN BELT FOR LNDG. I BELIEVE HE COULD HAVE INFORMED FLT ATTENDANT BEFORE OUR DEP, BUT MAY HAVE NOT WANTED TO DRAW ATTN TO HIMSELF. IT WOULD, AT THE VERY LEAST, HAVE FORCED US BACK TO GATE TO FIND A SOLUTION. I'VE TALKED TO MAINT AND LONGER BELT STRAPS WILL BE INSTALLED IN THIS NEWLY DEVELOPED ACFT.
