I'm sure some people will still fly, but all the airlines would go out of business, so it won't matter. Perhaps we can go back to sailing caravelles across the ocean.
Until matter teleporters become a reality, along with the associated existential questions of whether you die at the moment of teleportation and all that.
Even if we get over the existential issue, the security risks there would be pretty big too. What if a hacker just makes the thousands of people mid-teleport disappear? Is it predefined point to point, or can you teleport anywhere? If so, can we prevent people from teleporting anything into anywhere?

Well, there's a game called FTL (very good Roguelike with real-time ship-to-ship combat) [0] that has teleporting bombs as a distinct class of weapons... So of course, it's not hard to imagine that matter teleporters could and eventually will be used to great offensive and invasive effects, depending what the laws of physics allow.
