The point is that others can do it so anything listed here about how hard it is can be disregarded as an excuse. Give me a month and a budget and I could improve this. It's just a process. And I know nothing about running an airline. If BA wanted to sort this out, they could. This is another example of a business accepting mediocre service because the bookings keep coming. But in 5-years time when the LH fleet arrivals restore seat numbers to pre-covid capacity, I am speculating that filling all those seats with a decent return may be harder as people defect to those airlines that didn't sit on their hands wailing about the effects of Brexit,

Nothing is beyond the wit of human ingenuity. Except desire.
