How risky is it to add an additional segment to an award ticket? Flying to Dubai next month as a family of 4, currently booked as two separate tickets: SEA-DOH in J (AA award), DOH-DXB in Y (cash booking).
If DOH-DXB award space opens up, is it pretty simple for agents to add that segment without disturbing the SEA-DOH segment? Would prefer SEA-DOH-DXB as a single ticket for simplicity and to save money, but worried about them messing up the longhaul segment somehow (e.g. due to an untrained agent or technical glitch).
