Just flew ORD-DEL on AI. The person managing the check-in line was asking for PCR test results. I and a few others pointed out that the rule had changed. It was met with sarcastic comment "Sir, you know everything etc.". Ridiculous. The check in agent did confirm that they were checking for PCR test first and if not available, vaccine card could be shown. CDC vaccine was being accepted.

The level of distrust in AI and Indian government was telling. Everyone in the line around me, including me, knew about the rule change but everyone had gotten a PCR done.
