Sorry, my mistake. Thought flights to/from Libya were considered European flights wrt mileage earning.

As a comparison with UA's MP for TIP-FRA, W/U/S will all earn 1222 miles (but a U class connection from FRA to another European destination will earn nothing - 100% for W/S instead).

Again, if you plan to fly mostly in lower economy, I can only suggest you to choose UA over LH (I did the switch a couple of years ago and I'd do it again). In G/M/K/H/Q/V you earn the same. In Y/B or business, you're better off with LH (with more miles needed for *G, though).
