What to do in the case of a difference between Timatic and the Travel Ready Center? We are transiting Germany from ORD to Spain in a few days. I've read Timatic multiple times, and it appears to say that for transiting passengers, negative test not required if passengers have proof of vaccination that includes "One dose of Janssen and one dose of Moderna or Pfizer/BioNTech at least 14 days and at most 270 days before departure." We have met that requirement. However, when trying to enter vaccine info on the United Travel Ready Center, J&J/Janssen isn't even an option. Is this something that can be cleared up at check-in at the airport, or is it better to go ahead and get a test asap? FWIW, I booked and paid for a test through the UA site with a "testing partner," CVS, only to have CVS cancel said test several hours later. So now the only option is to go to ORD tomorrow.
