I'm flying LH tomorrow and was able to verify via ANA and AC websites that LH has 2 F class award seats available for my flight. I was even able to "reserve" these two seats using United's website.

I have an existing F class award reservation with ms. navi-c all on the same ticket with the same LH flight booked in business (no F availability at time of booking). When I call united to bump us up, they tell me they only see 1 F award seat available so they can't do the upgrade.

A clever agent, went ahead and reserved one of the seats and saw that poof another F class award seat was still available - so there really are two F class award seats currently available. THis is not phantom inventory, the United computer system just sees them 1 at a time.

They still claim however that without starting a new ticket (and losing all my connecting flights) they can't upgrade us to LH F. Are there any tricks / tips I can give the agent so they can force the system to see both award seats? Can we call Lufthansa? It seems like this is a computer glitch and since I've paid for F class award I was really hoping to check out LH F on the 747-8!!

Any help is greatly appreciated. If more info is needed please let me know!
