In Jan/Feb of this year we took these flights on Cebu: BKK-MNL, MNL-KLO, MPH-MNL, and MNL-USU and only took a carry-on (backpack), and the carry-on was never weighed. We were weighed ourselves plus our bag on the MPH-MNL and MNL-USU flights as those are ATRs and they needed a total weight. Our backbacks barely fit in the overheads of the ATRs, but did fit.
