Need Advice! Parents live in different countries and DD struggling.

[cfh]

Hi, I need advice so I can help my 12 yo daughter.
I'll try to keep it short. DD was born in London, I am Argentinean and dad is Greek (now divorced). Dad currently lives in Dubai with his new family and I moved back to Argentina with my husband, dd and twins.
When we first divorced, her dad moved to Belgium, Greece, France so she is used to travelling alone to see him but now that the distance is greater (19 hours flight), she is struggling. She doesnt feel she is normal for having 2 families so far apart, and wants we both live in the same country which is not possible.She travels at least once a year.
Has anyone been in a similar position, and if so, how do you deal with it.
Thanks!
