There are NO stupid questions. As noted already, just go to the airline site and plug in your itinerary number (or confirmation number). This will show you if the flight is still the same as when you booked.
An example for you.....
back a few years ago, I flew to WDW solo. My dh and dd were going to fly down to meet me 2 days later. Okay, no biggie. They had a connecting flight...Boston to NY to Orlando. My dh is absolutely anal about checking flight status...he checks right up until he walks out the door. Drives me nutty. Well...he checked the status, Jetblue site said the flight was 'ontime', so out the door they go. My dh always leaves earlier than most people...again, drives me nutty. So, they get to Logan about 2.5 hrs prior to departure. And what does he find when he goes to checkin, at the kiosk??? Flight has been cancelled!!! So, he goes up to the counter to see what the story is. Oh, no problem sir, we have put you on a later flight. Yeah, well that flight gets him into NY about an hour after his connecting flight departs...and that flight is the last one out to Orlando that night!!!! He is not happy!!! So, they ask if he has checked luggage. No, only carryon. Okay.....we can get you on a flight that is boarding right now...can you run??? Okay, lets go kid. So, they rush them through security and onto the plane....as my dh is telling our dd (11) that she may end up sitting apart from him. They are the last onboard, they are given seats together, and the doors close!!! Of course, they have to spend about 3 hrs in NY, waiting for that connecting flight.
But, moral of the story....check on your flights.
I have checked online to see that my flight has been cancelled but since it's a ways down the road, they haven't notified me yet. So, then you can be proactive and call the airline to make alternative arrangements....which are sometimes very advantageous for you.
