Just slightly off-topic, but I do have a RTW-related question burning under my fingernails.

First, when I got my ticket, I already felt lucky that they allowed CAI-BCN LHR-DXB-LHR MAD-CAI on my ex-CAI DONE3. (They forgot to count a ground-segment). Then, I was able to use two coupons for DFW-PIT-DFW rather than DFW-CLE-DFW without reissuing. First flight I had to go to PIT directly because of an immediate death in the family, so they rerouted me at the airport for free. That was very nice. On the flight back I changed my res to fly back from PIT and was advised I would need a reissue. I got to the airport too late and was very lucky nobody really looked closely at my ticket. So, no reissue. Then I got the ticket reissued in LAX to go HKG-FRA LON-DXB-LON MAD-CAI. That was perfect, since I was getting in trouble to get from LON to Germany. I am very very happy that I was able to go to FRA. But I also just found out that in fact that was another extra ground segment that was over the limit.

Now, the bummer. Checking-in for my feeder flight to HKG (a day later than planned, I had missed the flight I was ticketed for I asked wether I could go straight to FRA without going to CMB, since I had to cancel that trip. (I had a HKG-CMB-HKG in there for the miles). She said fine, but you have to pay the local departure tax. Whatever. So I just skipped two coupons, and still have them. Oh, unfortunately they aren't open-dated anymore, since the agent in LAX didn't know how to do those.

My question is, how high is the risk of getting caught if I try to use HKG-CMB-HKG in a couple of weeks? Is that asking too much from my luck? What could happen worst-case?
