iPad Air 1 is $120 to fix; newer ones are $260. The reason for the jump is that Apple moved to bonded technology (backlight, LCD, digitizer, glass is all one piece bonded from the factory) in the newer iPad Airs, so the parts are more expensive. The older iPads have separate glass/digitizer and LCD/backlight.
