With the oil from the German tanker there's no need for fuel to be sent from the middle east. In fact it'd be very dangerous to do so especially with the situation in the English Channel as shown in Boomer. Any transit would really need to be around the western side of the UK.
As for airpower, just because those craft are listed doesn't mean they're all operational, or even undamaged. As mentioned, parts are hard to come by as are munitions. Fuel is more plentiful than elsewhere, but still not in quantities that allow indiscriminate use (just look at the black market prices compared to IRL). My comment about air support being limited and anyone calling for it without a VERY good reason being hauled over the coals stands.
There's also a near zero chance of any flights between the middle east and Germany - just look at how many enemy units are between them. Sure, you could take the long way around, but I don't see too many aircraft on the list with the required range, certainly not without refuelling somewhere. That of course requires fuel to be available at a location where they aren't going to get shot at and the locals aren't wanting the fuel supplies for themselves.
In flight refuelling? Sure, they've got a couple of tankers, but just look at how many were required by the British Vulcan attacks on Port Stanley.

Also, tankers and cargo/passenger aircraft are extremely vulnerable and would need escorting, which of course requires even more fuel and tanker capacity.
And all this for what? One C-130 making the journey?
Now, lets get on to your misunderstanding of what I was saying about the "couple of banged up aircraft". What I was actually saying is that it probably all that would be available at any one time to a brigade commander, not the total of aircraft in the entire theatre. Also, just because there are so many aircraft in the theatres doesn't mean they're all available at all times - even just general routine maintenance will have some of them unavailable without prior planning for a large operation. As for the rest, well, as I've already implied, it's quite likely most will be out of effective range when needed, or even if they are in the area, may not be carrying the right mix of munitions (as an example could be carrying all air to air when a ground attack mission is called for).
Even today IRL it's not uncommon for air power or even artillery to be unavailable. There's often times when a battalions own mortars are not available for a company to call upon because they've been tasked to support another company. That situation would only be worse in T2K.
