I am looking at the US Airways Mastercard thru Barclays. For those of you who have the card or just know here is a question. Comparing the US Airways card versus something like Chase Ink or Capital One and using an across the board ratio of 1 mile per $1 spent, do I spend more or less money in getting redemption points for an airline ticket using a US Airways card versus the others. I know that I can get more points for certain purchases but I am just trying to figure out based on a 1:1 ratio am I charging more money on the card for a $300 ticket. In other words, Do I have to spend $2,500 before I have enough points to redeem for a ticket with the US Airways card and I have to spend $2,000 or $3,000 on the others to redeem for a $300 ticket.

I am just trying to figure out if I am having to spend more money on one card versus the others for the same $300 ticket.
