Macri also used to fly commercial long-haul (Air France too, if I recall)
What struck me as kind of interesting as that despite flying Lufthansa, that has a much nicer First Class cabin, the head of state opted "only" to go in Business Class. And would imagine that Lufthansa would offer an upgrade for him as a commercial gesture to the government given the "prestige" factor of carrying their business..
(Which by the way, is a grossly outdated and sub-standard product compared to nearly all the competitors flying between Buenos Aires and Europe except Aerolineas... even British Airways, KLM, Air France and Iberia give you a private suite with closing doors in Business these days).
