So we took off from SFO to LAX. Our flight was delayed several times in SFO. So we had very little time in LAX. That was American Airlines. The LAX to Heathrow was on British Airways. It was like recreating the wheel. They called us up to the counter and we had to explain the type D work/ residency visa AGAIN!! Then they wanted to physically see both the QR codes for entry into the UK and to enter Spain. Then she physically want the time of the collection of the RT-PCR test. Then we were cleared to fly to London.
Landing in London was uneventful and a bit confusing because our App does not tell us what gate we will be in. There was no immigration or COVID check and no one asked for the QR code yet! We went thru security and are waiting in the lounge. They post a time on the monitor of when we will find out our gate. Then we fly Iberia to Madrid. Keep you posted!!
