Planes were mostly used to attack sz 111, 112, Yugo and France. It is why sz 110 did not get hit. The other seazones west of England and east of Canada were hit by subs. No German fighters landed in southern Italy to help against Taranto which was an oversight.
UK would have thought twice if without the cruiser and facing three fighters. But maybe not, sometimes I like dicey battles (no risk no glory).
If the U.K. pulls that carrier out of the Med. then it can join the Indian fleet to help defend the Indies and if the U.S. is building enough navy in the Pacific the allies can put a lot of pressure on Japan. Japan cannot move south unless they bring a sizeable navy which will leave the home islands open to invasion by the U.S.
