It's worth noting that the reason most other airstrike maps use triggers to give other launchers airstrike properties is because most servers run item restrictions to prevent people from using airstrike on normal maps. So by not doing that your map probably won't be playable on many servers. If you don't care about it getting added to servers that's fine too, just pointing it out.
You should add tick HP regen:

In this case from eyeballing it, it looks like you have an orange world brush for sealing and a displacement for aesthetics? You should just sculpt the displacement and push everything either a little higher or lower than the orange brush so they're not exactly overlapping. This happens on quite a few jumps towards the end and is really easy to fix
There's also a weird visible playerclip brush at the end of the same jump that screenshot is from, most likely some sort of brush entity but playerclip should always be a world brush, you can just ctrl+shift+w when selecting it to destroy the entity and revert it to a world brush
Besides the technical stuff, my main complaint with the map is the plethora of random teleports, clips, displacement physics, and nonade that cover basically every jump. It really does ruin the idea of airstrike when you feel like you're fighting the map and trying to randomly guess what to actually do. Given that this is a "real tf2" jump map like competitive that sort of stuff is almost a given unfortunately, but if you wanted to spend a bunch of effort cleaning it up, as well as adding some more indications to things (like a func_illusionary overlayed with nonade or something to indicate where you cannot shoot) I think the map could benefit a lot from that. As it is right now I would say that the map is impossible to play for the first time unless you have a showtriggers toggle bind.
