It would be easier to give suggestions if you posted your favorite planes and what level they are at. I tend to upgrade roll, ascent/descent, speed and stealth on all planes if possible. For weapons I tend to upgrade standard missiles first and leave one slot for special weapons. I know some people don't like the dual purpose upgrades, but I use them whenever possible and have good results. My Wyvern with both dual purpose standard missile upgrades and bomb upgrade is devastating. It's at lvl 12 though so your results may vary.
