I am buying a rtw ticket that includes a AMM - LHR segment. I would like to purchase a AMM - DXB rtn ticket separately. (Adding DXB to the rtw ticket is not possible.) I would like to fly DXB-AMM-LHR on the same day and would like to check in in DXB for both flights (DXB - AMM and AMM to LHR) using both tickets.

RJ's Montreal office will not tell me if I can check in in DXB for my flight to LHR since I am on two separate tickets. I did call them twice and got the same person and same response both times.

I don't want to check in in DXB to AMM and need to clear customs, immigration, apply for a visa and then check in for the LHR flight. I need to be sure that I can check in in DXB for LHR before I purchase my AMM - DXB rtn flight, if RJ does not allow me to check in in DXB I would require different flight times and a longer layover or overnight layover in AMM.

Any advice will be appreciated.

Thank you.
