Cebu Pacific Air is successful in its marketing efforts as it is now considered the leading airline in the Philippines, toppling the long-time leader Philippine Airlines. People now choose Cebu Pacific when flying within the Philippines and even outside the country
Cebu Pacific's success started when it began giving out P1 (US$0.02) seats for domestic flights. Locals started flying within the country and so started Philippine Airlines' flight towards a bottomless pit. The P1-seat was then followed by US$10 seats for flights from the Philippines to select Asian countries, which also stirred locals to fly to Hong Kong, Singapore, Taiwan, Korea, etc...
I wonder if other airlines in other countries can launch a marketing strategy similar to Cebu Pacific's. By then, flying from one country to another will surely become affordable.
