Although US primarily rents out all of concourse D, they do not lease gates D8
and D10. I believe both belong to the airport now. UA
often uses D10 as an overflow, and overnight gate. ATA uses D8
as well. There are strong rumors running around that UA
will move to the D gates, which would free up some more space for TZ
, which they want desperately.
The biggest problem is that the leases for the gates are more expensive over there at D compared to C, so UA
will not move unless they get a favorable lease. They are in the negotiation process. I warn you though that this is a rumor, and not necessarily true. I heard it from a UA
gate agent in IND
a couple weeks ago.
If you have never designed an airplane part before, let the real designers do the work!
