Just returned yesterday.  I was quite amazed to find out that there was curbside check-in.  Not all airlines were but United was!  Lines are LONG!  But some seem to move rather quickly.  Security?  I was sorta amazed at that as well.  When we flew from Dulles, our bags were x-rayed, security checked everyone with the wand, looked through my husband's carryon bag.  But at MCO, none of that happened!  I didn't feel that MCO this year was any different than last year!  I was pretty relaxed flying although I had lost many hours of sleep and had many hours of worrying and trying to decide if we should go or stay home.
