Alitalia is running a limited time promo for new members who enroll in their loyalty program, MilleMiglia, by October 31st, 2013. New members will receive a bonus of 5,000 for enrolling in the MilleMiglia and either flying with Alitalia or using one of their program partners services within 3 months of enrolling.
Alitalia is a member of the Sky Team alliance and is a transfer partner of membership rewards making miles easy to accumulate. I didn’t find any terms specifically stating what constitutes using a program partners service. However, in the past Alitalia has counted transfers in from Amex Membership Rewards program as partner activity in respect to earning sign up bonuses so I see no reason why it wouldn’t count this time.
2,000 is the standard sign up bonus for Alitalia. So that makes this a pretty decent bonus. Back in March Alitalia had a 6,000 mile offer but it required flying with Alitalia in order to receive the final 2,000 miles. If you are not signed up yet, you might as well take advantage of this offer.
