This is why it is risky to bet on bubble rules not being enforced by an airline like BA. You just have to bump into one bad agent to spoil the day. While this is about vax certification check rather than bubble rule check, the problem is the same. This same idiocy is also coded into Verifly app. Especially for Indians that have long names and end up with those being expanded or not in different documents.
Just avoid BA until normalcy returns.
