Thanks to all of you for your great advice and posts, I am getting very close to clicking the button that says "Purchase Ticket & Select Seat" on the ATA web site! I have to decide tonight because my husband has to let his job know that he will be off a week in July....or not. I have already started talking to Jack and saying that in about a month he will be going on a vacation and he will get to see other doggies (that I know he will love)....I guess I am trying desperately to talk myself into it....I know he will be fine...I'm the one who has to get used to this idea.....thanks again everyone.....I really appreciate it!
