It’s funny...I traveled a lot internationally for work for several years in the mid 70s. For the life of me, I don’t recall how I got my airplane tickets. I think my company’s travel office prepaid them for me and I picked them up at the airport, but I’m not actually sure.
I DO remember arriving in the Philippines in the spring of ‘77 without a visa and had to talk my way in.
And tickets were paid for by cash or check in person.
I remember Human Resources leaving tickets on my desk in a brown envelope.
Oh— you visited my gf’s home country. But I’m guessing not Mindanao where she is from.
