Call your airline or go online and arrange seating in advance--otherwise you might not get to sit next to your "Significant Other"--this happened to me--the airline seperated us by several rows for a 3 hour flight (If you get this worked out waaaaay ahead of time you are OK) I bought tickets 3 months prior, but didn't follow through to make sure the airline put us together--thought I'd let you all know.
Putting the Green Flag up next to you at CSA means that you want someone to come by and bring you a drink (figured that out my last day)
