I recently read that in the old days (early 60s) the planes that crossed the Equator line would do some celebration when this happened. Cabin crew would give some pastries, and even liquors, to the passengers.

Is this still common in commercial flights?

While researching I found information about the [Line-crossing ceremony](https://en.wikipedia.org/wiki/Line-crossing_ceremony), but this is *an initiation rite (...) that commemorate a sailor's first crossing of the Equator*.
