To me, if you are going to "increase speed" for commercial travel, we need "Semi-Ballistic" "planes".
Basically, speed up using air breathing engines, then rocket takeover for a ballistic path to the destination, landing similar to space shuttle, but powered. Anywhere on the planet in 90 minutes or less.
