Examples:
Lifting an alien to bypass forward defenses for a surgical strike on the home base would give aliens back their mobility allowing them to strike anywhere on the map. You could also combine class abilities to benefit the team. Airlifting a dragoon above the human base would allow it to snipe stuff easier and maybe give the barbs more power (because of greater elevation and therefore more velocity). Doing a fly through of the human base with a marauder attached would allow you to zap stuff on the way without the risk of getting hung up on anything. Dropping a tyrant on the human base would just be cool. Flying grangers around the map would also give the aliens better mobility.
In practice:
To make it work in practice and not be the ultimate troll feature there needs to be mutual consent between both parties. We don't want people airlifting tyrants into bottomless elevator shafts for shits and giggles. We also don't want to have everyone using the flying alien to be forced to use the airlift ability. Especially if airlifting teammates slows you down or otherwise impairs the fun of it. I'm thinking the one doing the airlifting needs to somehow allow it with a on/off switch and the one being airlifted can jump on/off at any time they want to.
Also. Air Raid!
