I have done the 7:05 flight before and usually arrive at the airport between 4:45 and 5:00. We usually have enough time to sit and have breakfast once we get through security.
The security there can be tricky sometimes....we have had times for the early flights where we have got through quickly, then other times....whoa, took an hour or more to get through, then running to our plane. Therefore we try not to cut it too close, plus, what is another 15 or 30 minutes extra of sleep? Not worth it to be late in my books.
Have a great trip, we are on the evening flight tomorrow!
