Is this a joke?
70 aircraft of what type? What stats?

I can use B-2s and roam above the battlefield for as long as I want to.
If you use A-10s or F-16s and expect to come out of it clean, then LOL.

Focus on high EW planes and make sure you have plenty of WW sorties before you send in your strike/bombers.
If you don't know how to use planes, just say it, but the air defences are hardly overpowering. Start with a round of artillery at points that you expect the enemy might have his best SAMs, then follow it with either recon planes or WW planes to deal with the SAMs. Then bomb with artillery any SAMs detected but not dealt with. Then WW again, then artillery and when you think it is safe, then send in the strike planes.
If you only have 2-4 sorties, then forget the above. Either focus on stealth aircraft or just don't buy any planes. The best thing about not buying any planes while the enemy has bought plenty of air defense units is that if you don't buy any planes, he wasted all those points.
And seriously, 2 sorties = 0 if the enemy has air defenses. Unless of course you get something like the B-2 or even F-22.

Hell, if the use of Apaches or other recon helos at long range so that the enemy use its missiles to them, then strike them with artillery. Then use your 2-4 strike bombers.
