Flying LH metal on UA Codeshare, check-in ATL
Hi everyone--quick question. I'm coming for an airport hotel at ATL and would like to drop my baggage at the domestic side of things from the Skytrain and hop the terminal train to the F terminal. Can I check bags with UA on the domestic side, or do I need to complete the check-in at LH counter? I suspect the answer is the latter, but figured it couldn't hurt to ask.
