If flying SFO-FRA-DXB do I need a PCR test within 72 hours of departure from my FRA-DXB LH flight or is within 72 hours of the SFO-FRA UA flight enough?
The UA Travel Documentation Center seems to want a test result within 72 hours of departure from the FRA-DXB flight, which means about a day less to get test results in SFO.
Is it 72 hours from FRA-DXB or from when starting the whole journey? EK website is not very clear.
