Ok this might be wrong thread but this question is about RTW ticket, Visa, skipping the last leg and CX so there are many forums where I could put this and I have to choose one

I`am in the middle of the RTW trip (EX-MPM) and now in HKG. I have to end this trip to Africa so my last flights are in couple of days HKG-MAD-SSG (CX-IB). My plan is to skip MAD-SSG leg but here`s the questions:

1.) I have 9h lay-over in MAD so can I just tell HKG check-in agent that I have been travelling so much (what is true) that I have so many gifts (what is true) to my friends and I want to get rid of those presents in MAD so I would like to short check-in my bags only to MAD.

2.) Can check-in agent see that I don`t have Visa to SSG and can they ask to see my Visa in the check-in counter and can that become problem?

3.) If they can see it from computer somehow or ask to see it can I say:

A) I will get Visa when I am in Madrid. (Sunday so don`t know if they believe this).

B) Tell them that I don`t need visa because I will re-route myself in MAD to CPT and with my passport I don`t need visa to CPT (true). And this is flexible ticket so rules allows it (not sure if they allows it in the middle of the transfer when I can`t make stop-over anymore..)

C) say that i have 2 passports (not true) and I have visa in another one. I travel so much that i have to have 2 passports because another one is alway in embassy to waiting some visa and my another passport is in my parents summer house in Madrid.

4.) Can they see that I already have ticket with another OW carrier out from MAD for the next day (I have..) and ask how I can continue to SSG if I have ticket out of MAD for the next day.

5.) they don`t ask visa but wont let me short check-in my bags so I just go to the counter in MAD after first leg and say them that I don`t fly the last segment so they wont put my bags forward. What happens?

6.) Am I thinking too much


Thank you!
