You may like the Barclaycard Arrival Plus™ World Elite MasterCard®. It will give you 50,000 bonus miles towards any flight on any airline if you spend $3,000 on purchases in first three months. The card will allow you to earn two miles on travel purchases and on all other purchases as well. Miles can later be used towards cost of flights allowing you to save on travel. Every time you redeem your miles for travel, 5% of redeemed miles will be returned to your bonus miles balance, which you then can use for next redemption.
