Will Travel Insurance Cover Flight Cancellations and Delays Effectively?

So, I recently bought a Travelex essential plan for my upcoming trip to the Orlando theme parks. I found the coverage details on a SquareMouth page. Here’s the scoop: I’ve got an evening flight booked with a budget airline that’s nonrefundable. The plan is to spend three full days at the parks and stay four nights at a hotel before heading back in the afternoon. The park tickets and hotel reservations are nonrefundable by the departure date. My travel goals? I want to enjoy the parks for over two full days and get back home without a delay of more than 8 hours, with a midnight arrival. Canceling the trip would be a major bummer since vacation days are precious to us.

Now, let’s get to my burning questions:
1. Will insurance cover flight cancellations or delays caused by airline operational issues like staffing shortages? None of the plans I’ve checked clearly state coverage for operational issues.
2. If a few days before departure, I get an email saying my flight’s canceled with no other options from the airline, will insurance cover alternative transportation to my destination?
3. If I get a cancellation or delay notification on the departure day before I leave for the airport, does my plan coverage kick in then? Do I need to be at the airport to file a claim?
4. If I’m at the airport and the flight’s canceled for a covered reason, with no options from the airline to keep the delay under 12 hours, does the insurance cover alternative transportation ASAP?
5. If my rescheduled flight is the next morning (more than 6 hours later than the original departure time of 8 pm), can I book an overnight hotel stay or grab meals at the airport before 2 am (6-hour mark) and still be covered for trip delay?
6. If the rescheduled flight makes me miss the first night at the Orlando hotel and the first day at the theme park, do these count as nonrefundable expenses reimbursable by the insurance?
7. On the return day, if my afternoon flight is canceled or delayed over 8 hours, messing up my return to work the next day, will insurance cover alternative transportation?

I’ve dug through Travelex’s detailed plan description but can’t find clear answers to my scenarios. I sent them an email, but it might take a while for a reply. Any experienced travel hackers out there who can lend a hand? Your help is much appreciated!
