When I donated blood, they need my often b3cause Iām O-. They ran an antibodies test and I clearly have them because I had Covid Jan 2020. I have proof along with my Hospital stay in BKK. Good luck!!!
I had a huge problem with this airline too. They had a communication problem. I had the necessary documents but they refused to take them. I truly think they needed my seat that I had upgraded to in business classes. Very disturbing.
