Back-to-back ticketing is expressly forbidden by most airlines. It occurs when flight coupons are intentionally not used or they are used out of sequence in order to circumvent airline fare rules. Back-to-back ticketing includes the following two common scenarios:
Scenario 1: Coupons Not Used Suppose John wants to fly SFO-JFK April 11 and return April 13. The usual cost is on the order of $2000, because no Saturday night stay is included in the trip. The same airline offers a special fare of $400 round trip, provided John books 14 days in advance and stays over a Saturday night. John decides to buy two tickets:
April 2000 Su Mo Tu We Th Fr Sa Ticket 1: SFO-JFK April 11 (A) 1 JFK-SFO April 16 (B) 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Ticket 2: JFK-SFO April 13 (C) 16 17 18 19 20 21 22 SFO-JFK April 17 (D) 23 24 25 26 27 28 29 30
John plans to use (A) from Ticket 1 and (C) from Ticket 2 in order to complete his round trip itinerary. Each ticket costs $400, for a total of $800, so he saves $1200 off the cost of a full fare $2000 ticket. He does not use coupons (B) and (D). Note than John uses the first segment of each itinerary, because failure to use the first segment may result in the airline cancelling the remainder of the itinerary.
Scenario 2: Coupons Used Out of Sequence Suppose John wants to fly SFO-JFK April 11 and return April 13. He wants to make the same trip the next week, that is, leaving April 18 and returning April 20. Normally each round trip ticket would cost $2000, for a total of $4000. As in Scenario 1, the same airline offers a special fare of $400 round trip, provided John books 14 days in advance and stays over a Saturday night. John decides to buy two tickets:
April 2000 Su Mo Tu We Th Fr Sa Ticket 1: SFO-JFK April 11 (A) 1 JFK-SFO April 20 (B) 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Ticket 2: JFK-SFO April 13 (C) 16 17 18 19 20 21 22 SFO-JFK April 18 (D) 23 24 25 26 27 28 29 30
John plans to use all four segments from these two tickets, but in the following order: {A C D B}. He thus makes the two trips for $800 instead of $4000, and saves $3200.
The airlines are strongly opposed to back-to-back ticketing for the financial reasons you can see from the above examples. Whether back-to-back ticketing is actually illegal is a question you can ask your lawyer. You should be aware that back-to-back ticketing is against the rules of most airlines' frequent flyer programs. If an airline catches you using back-to-back ticketing, they may take away all your frequent flyer points and any status you have in their frequent flyer program. They may also charge you or your travel agent the full fare for both tickets. If you buy both tickets on the same airline and provide your frequent flyer number, it is extremely easy for the airlines to link your two reservations and discover what you're doing. If you buy each ticket on a different airline, it may be harder for the airlines to find out.
Back-to-back ticketing is very different from End-on-End Combinations, which are allowed by most airline fare rules. End-on-end combinations do not involve duplicate city pairs, but rather are used for fare construction via an intermediate city point. Tickets purchased with end-on-end combinations are used in the proper sequence.
