Thank you all again for your comments.
Please rest assured I would NEVER think of taking the earlier advice literally, and that was even before Thursdays' events. If I did try to go in and introduce myself I would expect at the least to find myself tied up and trusseted down an emergency slide to an awaiting police vehicle. I would also imagine that the airline in question may not be too keen to let me fly with them again, and quite justifiably so.
Wish you all the best with your work in these difficult times. You really do a brilliant job.
