What should passengers know about transferring through airports in countries with quarantine rules?

Passengers transferring through airports in countries that enforce quarantine measures should be aware that many countries require transit passengers to also undergo a 14-day quarantine. This poses risks such as lengthy layover times and potential flight cancellations, as highlighted by experiences shared in the comments. It is crucial to confirm all travel arrangements and regulations before flying to avoid complications, like being stuck at an airport due to border closures.
