As dangerous as the fighters were once Allied long range fighters became available
they were nothing compared to the Flak defenses. In 1944 Flak accounted for 3,501 American planes destroyed. More flak guns gradually appeared, mainly the 128mm (5 in) German Flak accounted for 50 of the 72 RAF bombers lost over Berlin on the night of March 24th, 1944. An incredible 56 bombers were destroyed or crippled by flak during a B-17 raid on Merseburg in November of 1944. (Data from Flak History Page)
Suffice to say on D-day there were only 300 Luftwaffe fighters to oppose the Allied landings in France and IIRC, 500 on the Eastern front.
See post above, plus a relatively few night fighters were still extracting a toll.
It was more like better trained American pilots. A perfect example of this was the amount of aviation fuel allotted to the training of pilots. Toward the last nine months of the war, they were sent into combat with only one-third of the training hours actually required because of… fuel shortage.

From the U.S. Strategic bombing survey…
…Production from the synthetic plants declined steadily and by July 1944 every major plant had been hit. These plants were producing an average of 316,000 tons per month when the attacks began. Their production fell to 107,000 tons in June and 17,000 tons in September. Output of aviation gasoline from synthetic plants dropped from 175,000 tons in April to 30,000 tons in July and 5,000 tons in September. Production recovered somewhat in November and December, but for the rest of the war was but a fraction of pre-attack output… Consumption of oil exceeded production from May 1944 on. Accumulated stocks were rapidly used up, and in six months were practically exhausted. The loss of oil production was sharply felt by the armed forces. In August the final run-in-time for aircraft engines was cut from two hours to one-half hour. For lack of fuel, pilot training, previously cut down, was further curtailed. Through the summer, the movement of German Panzer Divisions in the field was hampered more and more seriously as a result of losses in combat and mounting transportation difficulties, together with the fall in fuel production. By December, according to Speer, the fuel shortage had reached catastrophic proportions. When the Germans launched their counter-offensive on December 16, 1944, their reserves of fuel were insufficient to support the operation. They counted on capturing Allied stocks. Failing in this, many panzer units were lost when they ran out of gasoline. In February and March of 1945 the Germans massed 1,200 tanks on the Baranov bridgehead at the Vistula to check the Russians. They were immobilized for lack of gasoline and overrun…

And Speer’s report to Hitler…
The first massive raids on synthetic plants was flown on 12 May 1944 and directed against five plants. Other raids followed successively and continued into the spring of 1945. The severity of the raids was immediately recognized by the Germans. Between 30 June 1944 and 19 January 1945, Albert Speer directed five memoranda to Hitler which left no doubt about the increasingly serious situation. Speer pointed out that the attacks in May and June had reduced the output of aviation fuel by 90 percent. It would require six to eight weeks to make minimal repairs to resume production, but unless the refineries were protected by all possible means, coverage of the most urgent requirements of the armed forces could no longer be assured. An unbridgeable gap would be opened that must perforce have tragic consequences.
Continued attacks also negatively influenced the output of automotive gasoline, diesel fuel, Buna, and methanol, the last an essential ingredient in the production of powder and explosives. If, Speer warned, the attacks were sustained, production would sink further, the last remaining reserve stocks would be consumed, and the essential materials for the prosecution of a modern technological war would be lacking in the most important areas.
In his final report, Speer noted that the undisturbed repair and operation of the plants were essential prerequisites for further supply, but the experience of recent months had shown that this was impossible under existing conditions. Behind Speer’s warnings was his awareness that once production of fuels was substantially curtailed, once reserves and the fuel in the distribution system were depleted, the Germans would be finished and the end could be predicted with almost mathematical accuracy. In a way, Speer was merely echoing the prophetic utterance of Field Marshal Erhard Milch from the summer of 1943:
The hydrogenation plants are our most vulnerable spots; with them stands and falls our entire ability to wage war. Not only will planes no longer fly, but tanks and submarines also will stop running if the hydrogenation plants should actually be attacked.
A perfect example of this was the amount of aviation fuel allotted to the training of pilots. Toward the last nine months of the war, they were sent into combat with only one-third of the training hours actually required.

Again from the Strategic bombing survey…
“Before the Combined Bomber Offensive the German aircraft industry had at least a 100% excess capacity of plant and equipment. This is indicated by the fact that single-shift operation of most facilities was normal procedure prior to 1944.”
In 1944 the Speer Ministry reported to Hitler that 39,000 aircraft were produced, of which 26,000 were fighters. There are 17,000 German aircraft (8,000 fighters) which the USSBS could not account for based on the number of aircraft delivered and the number destroyed. It was known that Hitler demanded miracles from his subordinates. Under these circumstances it is not entirely impossible that Messrs Speer and Seur, controlling aircraft production, “rigged” their accounting to make a satisfactory showing. The conclusion is than nowhere near 39,000 aircraft were produced in 1944.
“Strategic bombing forced the dispersal of the aircraft industry. This disruption alone paid the cost of Allied bombing. Disruption of production was caused by the physical movement of goods and machinery, the loss of efficiency due to the dilution of management, an increased load on the already overtaxed transportation system were all factors in the final result. In the end dispersal defeated itself, because once the transportation system failed, it became impossible to keep final assembly points fed with the necessary component parts and sub-assemblies to produce finished aircraft. It was largely after that system failed that they decided to re-centralize the plants underground, for efficient and economical operation. This decision came too late to be effective in the German war programs but the cost of the effort added tremendously to the strain on the national economy.”
“Until early 1943 less than half the available capacity was utilized in the German aircraft industry. The industry was coasting along on a one-shift per day basis. The big push for expansion started in 1943 when the German High Command realized the potentialities of the Allied air attack. The realization came too late. The weight of attack that was delivered late in 1943 and early in 1944 set back production plans by many months and denied the German Air force some thousands of aircraft at a time when it needed them most.”
And…
“By the end of 1944 disintegration of the entire economy had set in. Transportation was disorganized to the point that essential materials could not be delivered to the manufacturers, nor could finished products be taken away. Airframe assembly plants, although relatively invulnerable to direct attack because of dispersal and underground installations, could not get deliveries of engines, accessories or sub-assemblies. Centralized planning broke down completely. Production of aircraft fell precipitously to a point far below the normal requirements of the German Air Force. By war’s end the manufacture of aircraft was at a standstill.”
