Another compromise in system.
The current money based system does have it's features that are good. I don't like that most bases on the map are utterly useless, and the long distances involved does sometimes knock out casual play.
My suggestion is to keep the money system in place, up the total money a bit but make certain planes available at all fields on their perspective sides.
The less effective planes for each side. Like the P40, P39, F4F on the allies side, and maybe the A6m and M202 on the axis. Either for free or, for a different price. For instance. P51's are 50 K. So say the allies spend 40 k to put P40's at 3 bases. Essentially drop the price of the early war or pre war rides down to the bottom. Like 10-20k depending on capability. or even free as I said earlier.
Or something like a separate support budget. Give each side another 100K each round that can only be spent on ground vehicles, support aircraft these older obsolete fighters, and maybe radar. Then fix in the particular aircraft available for purchase with these funds. That 100k is a fixed amount and doesn't change based on the results of the war. so both sides can at the very least be able to resupply and put up a basic fight each round.
These older planes would undoubtedly be placed at forward bases on both sides.
While the current point system can be spent by both sides, on the bigger bombers and the popular LW rides, which are usually placed a little further back in the lines the way they are now.
The reason I like the separate funds for these support type air frames, is because if you just give both sides more cash to work with, they'll simply buy more LW rides. This way yes both sides do get a little more funds to work with on LW rides, about 1 base worth of them. You also create a front line war for the EW rides. The LW fans can still fly their LW choices, just have to travel a little bit farther to do so. While at times like tonight where the allies have knocked out most of the allies usable late war bases, the axis could still up in something. Even if it's just zeroes, and m202's.
