After having a look on an article about air transportation in VN vnexpress.net/khong-can-them-hang-...

I have in mind a question of how expensive the airfare is in countries around VN (cost per kilometer). Then I got the research from rome2rio that could give me a satisfied answer even more info ( link for more detail) (against on data of economy class only that I think is closer to cattle class and adding fees on everything from luggage to seat assignments).

Year of report was 2018 then I gonna list out number of carriers in south east Asia countries:

• Vietnam 4 carries
• Thailand 10 carries
• Phillipines 6 carries
• Myanmar 4 carries
• Malaysia 4 carries
• Indonesia 9 carries
• Cambodia 4 carries
