Multi stop Air Ticketsnon-stop tickets
The trick is known as "hidden-city ticketing", and you should learn a lot about it when searching for this notion. By booking a booking for FLL->ORD->STL, the carrier undertakes to take you from FLL to STL. When the FLL-ORD is cancelled for any reasons, it is possible that they redirect you on an alternative trip via another target - e.g. a FLL->STL trip directly or via another town, e.g. FLL-IAD-STL.
Well, it's not like they'll find you and make you go to STL, but... once you jump a stage of a route, they'll void the remainder of the journey you book, plus the ride back tickets. When you book a flight, you actually sign a kind of agreement with the carrier and the carriers have specifically introduced "fare and fairness clauses" which state that they have the right to void the remainder of the flight, punish you and even expel you from the carrier.
Although the only instances they would prohibit or punish would be for recidivists. You also usually have policies that prevent you from purchasing a new one-way reverse travel if it returns on the same trip, so you will be forced to transfer charges if you wish to alter your departure date/time.
Thing is to review the regulations of the carriers and be cautious. Well, if it's a one-way ride, it should be okay. However, if it is a roundtrip, you may lose the part of your journey that you have made on the way back if you do not use all the routes on your outward journey. My suggestion is to consult with the carrier in advance, unless you are prepared to lose the remainder of your route.
The majority of airline companies still bill you for this second route even if you try to cancele it. If, however, as I assume you do, you get a cheap ride this way, then it' gonna be awesome, then do it! Ticket (s) may not be bought and used at a first point of embarkation on the Ticket prior to the Passenger's effective point of disembarkation or at a point further away than the Passenger's effective point of disembarkation, even if the sale and use of such Tickets would result in a lower price.
It is known as "Hidden Cities Ticketing" or "Point Beyond Ticketing" and is banned by the UA. When you have no luggage, you agree to lose the entire value of your tickets if you do, then you should do it by all means. However, very few airline companies leave you the remainder of the journey, even if you have not appeared in any of the sectors.
Those carriers that have such versatility and I am 100% positively disposed are WestJet and AirTransat. She had a multi-range airplane (around the world) that was running for over a year. Flying Dublin with another carrier to Amsterdam, she consulted the Lufthansa before the Dublin-Munich stage - she economised on the transaction because she had a paying but unoccupied passenger slot.
They canceled the whole remainder of the tickets. Nominal the smallprint allows them to do this, but they did not lose anything at all on the deal and made a net profit. needless to say* that my subsidiary has succeeded in reinstating the other leg, BUT that's what airline companies can do or try to do.
There was no additional connection with them and they were informed in beforehand and they were saving moneys. Doctor McMahon is very cute, very courteous (usually), very competent, and can even take over a pure carrier. Originally her goal was RT Denver/Milan, but she really had to be in London on Sunday, so she didn't notice her last stage of the journey (Paris/Milan).
Instead, she bought a Paris to London ticketing from the same on-line rebate airline, which brought her there on schedule. She canceled her plane back without warning, and was compelled to buy a $1,000 one-way Milan/Denver fare, and also has a missed date at the airfield.
Looks like AirFrance was selling her tickets to someone else. So...AirFrance was paying twice for the same place and then selling another place to the same person so she could come home. This is not, however, a good commercial practise on the part of the carrier. At the very least they could do was make her pays a charge and give her a place on the next return trip.
