The Spring Cash & Miles only applies if you fly between April 10 and June 9, 2007. Not only that, but all travel that involves the Spring Cash & Miles must be completed by June 12, 2007. The tickets must be purchased no later than May 26, 2007. But what if you aren't flying until late June? Is it worth waiting until the Summer Cash & Miles to redeem your miles for a cheaper flight to Europe? I suspect that more people will travel during the summer, so it will be hard to find a less expensive flight to Europe without a frequent flyer discount. Has anyone had WorldPerks long enough to know whether or not the Summer Cash & Miles is worth waiting for? Or should I just go ahead and buy a ticket to Europe and put more miles on my account? Thank you in advance for your responses.
