I've the following trip booked.
Outward: New Delhi -> Madrid -> Sao Paulo
Return: Lima -> Madrid -> Delhi
The New Delhi -> Madrid and Madrid -> Delhi leg is done by Air India. The Madrid -> Sao Paulo, Lima -> Madrid leg is covered by LATAM. The travel agent issued one ticket but I have two separate PNRS. Both airlines are star alliance members. Can I check in all the way through?
I ask, as the traveller doesn't have a Madrid visa. Air India says she should be able to check in all the way through, LATAM says she cannot.
Regardless, does the traveller need a transit visa to go change flights? We can try managing with just Cabin luggage.
The traveller is an Indian Citizen, with no other residencies or permits for any other country apart from a 10 year valid Canadian Visa.
