Back in 1993 I had a ticket called 'Delta Air Lines Travel America Standby Airpass' that allowed me to take an unlimited number of flights on Delta Airlines within a 30 day period. 60 days were available as well.
There were some conditions:
- You had to purchase the pass along with a transatlantic flight (possibly other long distance flights into the U.S. worked as well and they did not necessarily had to be with the same airline)
- You could not be a resident of the U.S. or Canada
- You could only use flights within the continental U.S.
- Your seat was not guaranteed, when showing up at the airport you would get added to the bottom of the stand-by passengers list, but most of the time, this was not a problem.
I know that at the time other airlines besides Delta had the same kind of passes, but do they still exist today?
It seems today air passes work differently, you have to buy coupons for a predefined route. The price depends on the distance and number of flights. An example is the Star Alliance North America Airpass
That's not what I am looking for, I like the unlimited 'Fly as much as you can' pass.
If there is a positive answer to this, it may also be a good answer to the question 'Sightseeing the USA by air'
