At some Schengen airports, pairs of travellers with mixed EU/Schengen + non-EU/Schengen citizenships (e.g. a German + a Canadian travelling together) are able to use the EU passport lanes together (i.e. both people together present their passport/ID at the normal passport checks for EU citizens, as opposed to the E-gates which the non-EU/Schengen citizen can't use).

Does that work at FRA too? (Or is that even a universal Schengen thing?)
