It's the 'if your plane gets off the ground' part I'd be praying for.
If the flight gets cancelled its a whole other game plan. If I were you, jic, I'd have a Plan B in my back pocket. Nothing involving spent dollars or canceling existing plans, but I would have alternate carriers and flight numbers available jic they might be needed and assuming there are other route options available that you could use if you had to.
We never want to think it's our flight that might get cancelled but it does happen. We had friends who lost three days of their vacation a couple of years ago.
Their well planned and much anticipated Valentines Day dinner at Spiga ended up at one of the JFK area hotel restaurants. All the other flights up to that point were already fully booked so they had to wait it out in NY instead of sunny SXM. And on top of losing half their first week, they had to pay for their own hotel in NY since it was a weather related issue that kept them grounded, and it was too far for them to travel back home in the weather mess that caused the problem in the first place.
At least you're near the airport should the worse happen, but I wonder if a twenty-four hold on seats for for the next day flight would help in that particular situation. I know AA allows you to book and hold tickets for 24 hours and they automatically cancel if not purchased but I don't know if it would work in this situation or if your carrier does this in the first place.
Or - just think positive MY PLANE WILL FLY! MY PLANE WILL FLY!! I sincerely hope all goes well for you and all who are flying tomorrow. <img src="http://www.traveltalkonline.com/forums/images/graemlins/handshake.gif" alt="" /> <img src="http://www.traveltalkonline.com/forums/images/graemlins/handshake.gif" alt="" />
