Thank you for advice..Knew you guys/gals were good.,So far found good fare ORD-FRA with UA (not upgradeable).. and can use miles of 30M to go FRA-AGP with LH...But on return seems must be overnite in FRA..So would need budget hotel in FRA one nite in June..We are retired seniors..found an apt. Costa de Sol reasonable cost..Good exchange rate..
