Private jet charter companies have nothing to do with border control. The passengers will have them checked but not lined up in a queue with other peasants.

Did you ever saw any politicians using their passports or crazy rules when they fly?
NONE.
Why people do not ask these reasonable questions?

Indeed are some private jets that do not ask questions...
It's all about a contract and that contract rules and agreement.

Yes perfectly fair, wondering if private jets have same requirements
