One way ticket to LIM - issue at check-in or immigration
I hold a Singaporean passport and have purchased an one-way ticket from LAX to LIM (via ATL) on DL.
My plan is to travel overland to Brazil and I don't have any air ticket out of Peru. I have a ticket back to SIN out of GIG though.
Will there be any issue at check-in or at the LIM immigration?
Thanks for the help in advance.
