Nested round trip?
 

Hi All,
Pardon the noob question.
I am looking to book a round trip within a round trip. Is it called nested?
Basically i want to travel:

A to B, stay 3 days,
B to C stay 3 weeks,
C to B, stay 3 days,
B to A, go back to work.

Because of cost of stopover flight (travel for 4 people), i want to book on round trip A-B, and another round trip B-C within the time of the first one.
A-B...(B-C................C-B)...B-A

If it is not allowed, how do airlines detect and enforce it?:confused:

A thousand apologies if you are being asked this for the millionth time.
Thank you all.

What you want to do is perfectly fine. You will not be sent to airline jail.

Since you plan 3 days at point B you've also removed pretty much any chance of there being an issue of not being able to make your flight back home so I think you've got a solid situation here.

Enjoy the trip.

That itinerary is not a problem. It would only be a potential problem if the nested trip was B to A to B and was designed to avoid a minimum stay requirement, such as a Saturday night stay. Even then, with so many fares now being one way, it is less of an issue than it used to be. And finally, if the B-C-B trip is on a different airline than the A-B-A trip, there would absolutely be no issue.

No issues at all. Done this for about 3 times in the last 2 year.
