But it isn't as simple as 'which routes now have a new incumbent operator'. Frequency and capacity must also be factored in. A route such as MAN-SOU now flown once daily by Eastern ATR72 cannot be considered backfilled from the FlyBe operation of upto six Q400 departures per day. Likewise MAN-EXT, now operating less than once daily with Blue Islands. Many other 're-adopted' routes across the former FlyBe network also see this pattern of just one flight per day or fewer replicated. Obviously, covid-related demand supression is a major factor shaping the current regional networks, but as confidence in travel grows and interline opportunities open up again, additional frequencies will be required. Whether or not these can be offered by the new incumbents (who generally have very limited fleet availability) or whether there is space for a second operator to enter the market remains to be seen.
