If you are too junior and on reserve and keep getting Lagos, then you can bid the 737 and make sure you never see that place again.
General,
Don't knock LOS until you try it. Other than holidays (Thanksgiving) the trip is not a junior trip at all.
Let's see...it is a "four day" that doesn't sign in until 9 pm on day one, and finishes at 0530 on day four. It is worth nearly 25 hours, and you sleep halfway there in the condo (infinitely better than any crew rest seat in the cabin). Granted, Nigeria is a 4th world dump, but after the armed escort, you get to a pretty nice hotel around 5 pm. Meet by the tiki bar and the pool about 6:30, and enjoy a Star or Gulder or two. If it is buffet night, enjoy a world class buffet (food all imported from Europe) poolside with the calypso band for your entertainment. If it is not buffet night, enjoy a tasty kebob or pizza, or try the indoor buffet, Italian restaurant, or Irish pub inside.
Hit the rack about 11 pm or so. Wake up, work out in the very nice gym. Hang out by the pool after that (maybe ogle some European stews, it is hit or miss) and enjoy a late lunch. Take a nap, work on the computer, whatever, and pick up that evening. DAL gives you enough money as a credit to the hotel that you hardly spend any.
Then fly home over the mid-Atlantic--no tracks, hardly any traffic once west of Dakar, and if you aren't in the cockpit, you are once again snoozing in the condo.
Did I mention the trip was worth almost 25 hours? While I wouldn't want a steady diet of this (it's hardly Stuttgart, and no one is pretending that it is) doing one a month or per quarter is a fairly good deal.
That is, unless you are senior to me, then it sucks!
