Airlines may inquire about onward travel and require proof of return tickets (e.g., Turkish Airlines, Royal Air Maroc). Some passengers have reported stricter checks based on nationality, with instances where Russian citizens faced issues while citizens of other countries did not. Airlines like Emirates may also have specific transit requirements, particularly concerning routes involving Mexico. Flying from Brazil might present fewer transit complications. It is advisable to have booking confirmations for onward travel readily available. Policies can vary, and requirements may be easing.
