Back to Back or "Nested" Tickets - Discussion

Ticket validity: Compliance with terms and conditions of sale (link)

American specifically prohibits practices commonly known as:

• Back-to-back ticketing: The combination of two or more roundtrip excursion fares end to end for the purpose of circumventing minimum stay requirements.

<snip>

Where a ticket is invalidated as the result of the passenger's non-compliance with any term or condition of sale, American has the right in its sole discretion to:

1. Cancel any remaining portion of the passenger's itinerary
2. Confiscate unused flight coupons
3. Refuse to board the passenger or check the passenger's luggage
4. Refuse to refund an otherwise refundable ticket
5. Assess the passenger for the reasonable remaining value of the ticket, which shall be no less than the difference between the fare actually paid and the lowest fare applicable to the passenger's actual itinerary

Typically, these are tickets purchased to evade minimum stays such as seven days or Saturday night. E.g. Consultant John Doe flies AUS-SEA Monday, returns Thursday; he buys nested round trip excursion tickets using coupon 1 of ticket 1 outbound, coupon 1 of ticket 2 return, the coupons #2 the following week, etc. AA hates John Doe. AA wants Mr. Doe to stop it.
