Sure, bingo, 8 years in jail.
Under which country's law?
the airlines agents just need to sight some thing which shows you will board a flight within 3 months. Occasionally, they will note down the flight no and date on their computer.
No one is making a video tape of the the evidence you are handing over or making you sign any document that you will be taking this flight, you tell them. I dont even remember any one taking copy of such tickets.
I dont remember any country's immigration asking me for onward ticket. Only these airline agents are the nuicanse.That is the best way to deal them.
I don't remember any airline agent having wasting time trying to call the other airline to confirm the ticket no etc.
And I never heard anyone getting jailed for 8 years anywhere in the world for producing a 'fake' onward ticket. ( fake passport or fake visa..yes!)

When we used to line up to take visa at embassys in Congo, they always asked for confirmed return tickets at time of submitting the visa application. Always submitted, what we called 'dummy tickets' with fake ticket number and imaginary dates etc. Bingo. It always worked.

So Ruibilar, I usually value what you say on this forum..but for this ones..lets agree to disagree. i think you are drunk!
P.S : - The other solution I offer is to buy a real ticket on orbitz, cheaptickets or expedia on the date of travel and as soon you are checked in, just call up to cancel using their "24 hours, No questions asked free cancellation 100% refund' . This is 100% legal (well?!) but just requires some more time and use of phone at the airport. And there are usually long queues at customer care call centre of all these three sites.
