I booked a Lufthansa Flight leaving SFO at 2:20PM to Frankfurt on a Thursday. I was wondering what is the earliest time that I can check in at SFO so that way I can go up to the United International Lounge using my Priority Pass membership? How are the lines on Thursday late mornings/early afternoons?

Can I check in online and go to a Fast Bag Drop for Y class? How does this work at SFO? I already entered my Passport information to Expedia will this be forwarded to Lufthansa and will it speed up the checkin process?

BTW What are the complimentary House Wines/Beers and Spirits at United International lounge? Is it like the CO Presidents Club iwth Campari, Baileys, Red Wine White Wine, Budwieser Budlight etc?

Thanks
