Not sure if I should ask this as in a separate thread... I have a follow up question to those who did segment runs in the past.
In case of two same day itineraries like SEA-xxx-SEA and SEA-yyy-SEA (all operated by Alaska, obviously), what happens if the first arrival to Seattle is delayed and causes to miss the boarding to the second departure from Seattle? Do you know would they rebook on the next flight out even in case of two separate itineraries?
