Toryu the Qatar and United routes are the flights to other airline's hubs I mentioned earlier. The Air Berlin flights may have had reasonable load factors, but their yield is unknown. Given Air Berlin's losses over the years it is unclear how much money these and a lot of other routes were making. It is irrelevant now because there is no equivalent German airline likely to step in. Norwegian or someone similar might have given it a go in different times. But right now everyone is just scrambling to survive and starting a lot of new services is likely postponed to the indeterminate future.
