I have no current info, but rest assured that your company would not be sending their crews to Lagos if there was any doubt about safety!
When I was Cabin Crew in '61 and '62 on BOAC's Bristol Britannia 102s, we spent most of our flying life going up and down to Lagos at 16,000 ft, the then accepted FL
for Britannias! Great fun!
Lagos was never that friendly, but we were able to walk around, even at night time, without being harassed, but gather times have changed. Enjoy your trip - it's the company that matters, and the beer is good!
If you want to be bored, ask me about the Christmas when I exchanged two Beatle wigs (yes, there were wigs that emulated the Beatles haircut) with the local Carsberg rep, for six cases of a dozen pint bottles of the good stuff. Trouble was, the deal was finalised on the crew bus as we were leaving the Lagos hotel, but would you believe, we experienced engine trouble in Kano, so had to make a nightstop . . . ! Merry Christmas!
