I am a CFI, CFII, and MEI at a 141 flight school. I endorsed a solo student cross country and the student got lost and violated DFW class Bravo airspace. The paperwork was all in order and I am hoping I'm in the clear, but I only had 3 hours of instruction with the student and I'm concerned something might happen. I had picked the student up after one of the other instructors went on vacation. I wont slam you with details. Anyway if something bad happens and I end up with a violation on my record, do I have any chance of still getting hired by a regional/major in the future? I wasn't in the plane after all, but I'm concerned either way. Any guidance would be appreciated
