Dx advice
If this is your first time jumpseating, ask someone in your office about protocol.... it's important. Remember, it's the captain's decision whether you get on, but the gate agent can keep you from talking to the CPT. I've always had good luck by being as nice as possible, and simply asking "would it be possible to sign up for the jumpseat?" Have your ID and license ready for them, it helps to have your own pen, and get out of the way of paying passengers when you are filling out your form. Remember, you are in effect begging for a ride (which they don't have to give you) so being humble is the safest way to go. Some gate agents don't know, however, that DX'ers can jumpseat. If they say they don't take DX'ers, politely ask when they stopped. I've only had one problem with an agent like that, and the Captain intervened, which started an argument between them. I told them I 'd just go on another airline, and the CPT said "stay where you are, it's a matter of principle now", and I ended up getting on. If you're not in CASS, you will have to be a cabin rider, so they will have to have an open seat for you, but it's usually no big deal. Have a great time, and remember to thank the crew for the ride!!!!
