Quite new to this forum, I'd like to know if anyone could help me with a URL, which is able to book flights with "service classes".
I'm always in trouble booking flights on UA or LH, which both have different upgrade rules to business wether you book your flight in "B" or "Y" or other coach classes. Same problem with those "restricted business excursion" fares on all Star Alliance Partners. There is a "D" fare on UA and LH ("J" on AC), which is quite a deal - but no way in any booking system (to my knowledge) so far to get this class booked. Always get a "C" fare. Any Ideas out there ?
