Does anyone of you use that card for booking? How many miles? or is it related to cost amount? Thanks.

If you mean FFM that you earmed on US Air credit card , yes
We have flown twice from Washington DC,
National airport to Aruba.. either through Charlotte or Phila. and then done DCA over to Bon.. Both times it worked well. This summer we checked our bags in with DCA =BE or whatever they are today and took a cab downtown and walked around, To do it again, would use advice given on this site and go to a hotel and sit by the pool or rent a car and drive the island.

Oh boy times we pulled it off for 30 , ooo. Takes all day, but price wise is a good thing.. L

I don't understand. You mean it is not a set price? Sometimes it is more? How do you get the lower price? I have not yet committed to the card, and I'm trying to decide if it is worth the $90 annual fee to get "miles" DO you think the "bonus miles" you get when you first sign on count as "regular miles"? Thanks.
