Is it the same Alaska Air which just 20 years ago tried to sell in-flight voice calls on their in-plane phones for few bucks a minute, as any other airline did? Remember handsets in the backrest of the seat in front of you with the credit card slot on the side?
Yes, they and others in fact have changed their mind as the accessibility of this service has grown and can be expected to be used by someone easily for longer durations than before
Probably. Allowing people to stay connected on a plane is likely important, but now that "connected" can be "able to send WhatsApp messages" then the need for a phone is much reduced.
