The "Ber" months—September to December—are widely recognized for higher air travel volumes, especially in countries like the Philippines where Christmas celebrations start early. Studies and data from aviation authorities support this seasonal surge in flight bookings. According to the Airlines Reporting Corporation (ARC), holiday air travel spikes significantly during Q4, fueled by vacation plans, family reunions, and year-end corporate activities. The ARC, in collaboration with Expedia, noted that domestic and international flights during these months typically experience increased demand, with international flights seeing fare increases as travelers take advantage of year-end deals.
