Our wedding is on 3/31/12 and probably about 70% of our guests are from out of town. I was looking at flights today and noticed that flight prices for that weekend are already really high!!! From New York, they are about $350-400 for non-stop flights! I know March is one of the high season months but I guess I didn't expect flights prices to have already sky rocketed. Thought they would go up after the new year. Now I'm worried that none of our friends will be able to come!

I know some of our friends have already booked their hotels but I'm not sure if anyone has booked their flights yet.
We sent our Save the Dates out back in August. Do you think it makes sense for me to send around an email to everyone just to give them a heads up to book their hotel/flight arrangements sooner rather than later...? I probably should have done that a month or two ago but I didn't think prices would already be this expensive!
