Question about "nested" round trips
I recognize this is probably a noob question, but I couldn't find an answer quickly. Apologies if it's been done to death. I haven't had to look a this before.
Is it legal for me to buy two round trips, one AAA-BBB and one BBB-CCC, which would schedule like this?
AAA-BBB
BBB-CCC
CCC-BBB
BBB-AAA
It's a lot cheaper than buying AAA-CCC round-trip.
