Splendid - just returned from Nice two weeks ago on an ex USA freebie MFU European sector.

Needless to say the points and miles have not yet posted, though have chased telephonically.

There is some debate about the NCE lounge which is said to deny acess to non Silver/Golds even if travelling in CE, however, my experience was that as a Blue I was allowed in without question, although it was a quiet Sunday evening.

Take the cheap bus to the Promenade des Anglais and if the weather is good enough catch some lunch and potter back for your return flight.

Took the late flight back and sitting on the left of the plane had superb view of Paris and the Eiffel Tower lit up boldly in the centre of the city.
LGW crews are superb, and no danger of no food!
