Security wait times at SCQ for a 6:45AM flight

Looking at flights out of Santigo de Compestella outbound to US through Madrid with a 6:45AM departure time and hope you guys can share your experience (wait time) checking in for a flight. Flights later in the day or the next day are +$1,200 more for the 5 of us.

Thanks in advance.

Thanks. We were not planning on this trip, but my youngest son graduates high school and thought it would be cool. It will give me a taste of Camino life, and allow me to speak some broken Spanish. I will be done with Spanish 1 in a couple of weeks. Running joke in our house is that I will pass with an A and not know how to speak Spanish. I have already registered for Spanish 2 in summer B which ends at the beginning of August. I am still planning a couple of months in Spain in the fall when both boys are away at college (SJPD - Santiago, Finistère, Muxía).

I think we need to err on the safe side and get to the airport a couple of hours early. We may end up waiting a while and it makes for a long day back to the states, but we can sleep on the plane. We will have almost a 9 hour layover in Madrid, so I think we will check our bags through if possible or check them at the airport, catch a train into town, and have a lazy lunch before we depart Madrid.
