ATC delays like this are not in the airline's control.
Planning flights over capacity of the airport is within the airline's control, and from the long thread they seem to be planning flights without considering the capacity. The US ended up getting a new law about tarmac delays because of bad ground management during the '99 DTW snowstorm.
And it should be all one itinerary - it was booked by the travel agents for whatever agency flew her out. She managed to find a hotel far out and will make the travel agency sort it out.
