Used to be that 20 was the maximum amount, counting supplemental segments. No more; 16 is now the magic number. You can't exceed 16 overall, full stop.
The only way the 16 sector limit can be overridden is if the
airline changes something. Such as due to a cancellation.
eg, In 2008, I had booked a 16 sector LONE4 with NRT-MEL. QF canceled the
NRT-MEL flights after I ticketed, so rerouted me through SYD. Making it 17 sectors with NRT-SYD-MEL.
In 2009, I had booked a 16 sector LONE4 with a single flight number DEN(ORD)BOS. After ticketing, AA canned the flight and rerouted me via DFW, making DEN-BOS into DEN-DFW-BOS and upto 17 sectors.
