Out-of-Touch Travellers

We haven't flown since 2011, so we're a little apprehensive.  We're travelling to Rochester, NY to visit family, especially a cousin who is flying in from Germany.  But at least, we now have our boarding passes, calendar pretty well filled out, and suitcases almost filled.  What next?  Will the limousine service pick us up on time?  Will the plane be late?  With there be a car waiting for us at Avis?  Did we pack the correct clothes?  Time will tell.
