I've been to Thailand 6 times in the last 12 months without applying for visa .....just get a 30 day exemption each time .... However u mention u can only enter twice within 12 month period without visa ...has this stipulation been introduced recently ?
I understand ....but vietjet didn't explain why ? They didn't ask to see my bank account or any evidence to support myself . They just said it was a requirement . Some airlines are doing this others aren't . They should make it known when u book the tickets prior to getting to check-in..
