Looking at the ACL S21 report, interesting to see reference to "Fly Play" a new Icelandic outfit forming out of the ashes of Wow and securing slots to KEF with Icelandair doing the same.
Other reported new / significant changes incude
SATA International to PDL
Air India listed as operating to BOM.
and the much discussed JetBlue to BOS.
Obviously early days and how much of this lot not to mention the bread and butter stuff will actually come to fruition remains to be seen.
