I just came across this news about a Brazilian company that now accepts 3 cryptocurrencies (BTC, BCH and LTC) to book their tickets. The payment method is quite simple, just with a code in a screen, no complex technologies nor terminals. It is unclear how they handle network congestion and how many confirmations are required.

This is the source

I also seem to recall that there is an airport in Australia accepting crypto and at least one airline, but I don´t remember which one.

If anyone from Brazil could comment on this news it would be nice.
