Many of us here on FT make mileage runs often. For exampole, my wife needed about 10,000 airmiles to requalify on United for elite level ( Premiere Executive, ie, 1p.) a year ago. Soooooooo she flew non-stop on Luft. metal IAH-Frankrurt, had a nice dinner close to airport, and returned the next afternoon. (Yes she sleeps on plane with the aid of ambian.

We have both done a three day RT to Paris, three day RT to Vienna (Wien), etc. and since neither of us have problems with jet lag and even given that we are "seniors", we have fun and do not "overdo" as we know we will be returning again and staying longer in the future.

Have a great time in Paris...and remember you will be back.
