st: how can I group airport markets
Date

I have a large dataset on flights with information about origins and
destinations.
For example: origin - destination
LAX - MIA
LAX - MIA
MIA - LAX
MIA - LAX
MIA - LAX
LAS - LAX
LAX - LAS
... ...
How can I group LAX-MIA and MIA-LAX into the same market? If I use
egen market = group (origin destination), they will be grouped into 2
different markets. Another way is to sort the data into the same origins
to the same destinations, but I don't know how to do that either.
For example: origin - destination
LAX - MIA
LAX - MIA
LAX - MIA
LAX - MIA
LAX - MIA
LAX - LAS
LAX - LAS
... ...
Thanks!
