If the first flight in your trip is delayed past the 1-day limit of testing due to a situation outside of your control (e.g., delays because of severe weather or aircraft mechanical problem), and that delay is 24 hours or less past the 1-day limit for testing, you do not need to be retested. If the delay is more than 24 hours past the 1- day limit, then you will need to be retested.
If a connecting flight in your trip is delayed past the 1-day limit of testing due to a situation outside of your control (e.g., delays because of severe weather or aircraft mechanical problem), and that delay is less than 48 hours past the 1-day limit for testing, you do not need to be retested. If the delay is more than 48 hours past the 1-day limit, then you will need to be retested.
