Airline Policies and Denied Boarding: how it works in Brazil — first-hand

Airlines typically have policies to rebook passengers on the next available flight if a previous flight (on the same ticket) is delayed, but this may involve significant waiting periods, especially for less frequent routes. Consider booking flights with ample layover times or opt for airlines that offer more robust rebooking options. Always check the specific terms and conditions of your ticket and the airline's policies regarding delays and missed connections. For single tickets, the airline is generally responsible for ensuring you reach your final destination. However, the timing of this rebooking can vary, and if the delay causes you to miss a subsequent flight that is not on the same ticket, you may be responsible for the cost of a new ticket.

Qatar Airways is reported to be more lenient. The risk is often attributed to airline policies regarding potential illegal migration to the US. Travelers are advised to avoid Turkish Airlines if possible to mitigate the risk of being denied boarding.

During transit in Istanbul, passengers do not pass customs but must go through manual security checks at the gate, where they are required to present a confirmed return ticket and a hotel reservation.

Risk of missed connections is significantly higher, as separate tickets do not guarantee protection for subsequent segments if the first flight is delayed.
