        Wasn’t the use of an X an artifact of the standardization of airport codes into three letters? With airports already having two letter-codes appending an X to meet the new standard.

      Not sure what the “= =“ means, but PDX is the airport identifier for Portland. Portland is just “Portland international”. Sometimes the identifiers align closely with airport location or history, like ORD (Chicago) was built on “Orchard Place”, and Douglas manufactured aircraft at a facility there during WW2, so Orchard Douglas became ORD. Someplace like DFW is just Dallas + Fort Worth.

      Prob more than you wanted, but there you go.

        Math nerd to the rescue!

        “==“ is either math for constantly equal (there are no situations in which they are different) or programming for boolean equal, aka the question of are these two things equal.

            Moreover, in programming a single = sets the value on the left to the value on the right, while == (or in some languages ===) means to compare the values (and === is explicit).

            Then there are the various forms of not equal (!=) and greater than/less than or equal ( <=, >= )
