Yea, I posted over on BP about it too.
2018 wireless market share:
35% Verizon
34% AT&T
17% TMobile
12% Sprint
2018 airline market share (roughly):
18% AA
18% SWA
17% Delta
15% United
6% Alaska
6% JetBlue
Each industry has 4 companies controlling a vast majority of market share. If Tmobile/Sprint happens then that industry goes to 3 carriers controlling 98% market share. I don't think it would be unreasonable for that to set the stage for the airline sector to at least go to 4 airlines controlling 85% market share (Alaska and JB both being gobbled up by larger carriers).
