While waiting for a batch of excellent new questions from jlemon, I've a couple to throw to y'all. (They may be too obscure, but with this crowd you never know!)

A) In the Bermuda II agreement signed in 1977, 5th Freedom rights were granted to U.S. airlines to carry local traffic beyond the U.K. to four points within West Germany.

1) Name the three destinations in West Germany where only one U.S. carrier was allowed these rights

2) Name the one destination in West Germany where two U.S. carriers were allowed these rights

Bonus points: Name the airlines granted the rights for each West German destination.

B) At LGW, in the late 1980s (beginning '87/'88), a U.S. airline placed its code and flight number on a European airline's flight as a codeshare/interline service to a destination in a third country within continental Europe. Today, it would be tantamount to UA placing UA900 on an LH flight originating at FRA without using a separate codeshare flight number to indicate that it involves a change of airline somewhere along the route.

1) Name the airlines involved:
a) U.S.
b) European

2) Name the U.S. origin(s) and European destination

Bonus points: The U.S. airline's flight numbers for this service are still in use today from a U.S. city to Heathrow. Which U.S. city?
