CHAMPAIGN, Ill. — Illinois has joined more than 20 other states trying to lure Boeing’s production of the 777x airliner out of Washington state, but the company’s long list of requirements could prove expensive.

But beyond expense, aircraft industry analysts say Illinois — home to Boeing’s headquarters but very little of its production — doesn’t have what the company needs. Illinois is making its pitch amid an ongoing debate about when tax breaks and other perks for businesses make sense, another factor that could complicate the state’s case.
