Manchester bike airport parking

[newbuild100]

As above, do any of you guys know if there is anywhere safe/secure to park the bike for a couple of weeks whilst im on my hols. ?
(My flight is silly o clock AM and rather than burden my friends/family to get me there, I thought about going on bike)

Thanks

head for T1/T3 down to the roundaabout - dont go up the ramp (thru the roadworks)

at the roundabout 3rd exit for t1 valet and as you exit you'll see a big elec substation under the flyover the bike parking is behind/under this and about 20ft from t1 entrance and 5 mins walk to t3

concrete loops in floor and its got cctv
