Hi, folks, I have some Hungarian friends, currently living in Sweden, who are coming to visit California in April/May 2012. I purchased their air tickets on .bomb for travel on Continental Airlines. They have asked me to recommend which Star Alliance loyalty program they should join and credit the miles to. They are husband, wife, 5 year-old and lap infant. Much of their travel is intra-Europe, but they love to travel and have visited the Middle East a couple of times. They usually fly WizzAir, but we all though collecting miles would not be a bad thing since they're making such a long journey. The flights have booked into 'K' class. I want to have them join soon so I can add their FFNs to the reservation. Thanks for your suggestions!
