Thom Jurek of AllMusic gave Paper Airplane four-stars, describing it as melancholy, with songs revolving around themes of trial and perseverance. He also praised the cover versions of "Dimming of the Day" and "My Opening Farewell". He considered the album "polished yet authentic".[4]
Andrew Greer of Christianity Today also honored Paper Airplane with four stars, finding it "an exquisite eleven-song canon," and added: "Though their haunts are heavy-hearted, a tangible hope pervades Airplane, attesting to the band's spiritual sensitivity even without the band's usual faith song standout."[5] The album won Grammys for Best Bluegrass Album and Best Engineered Album, Non-Classical.[6]
