Note 6 — Commitments and Contingencies

As of June 30, 2018, the Company leased aircraft, airport facilities, office space, and other property and equipment under non-cancelable operating leases which are generally on a long-term, triple net lease basis pursuant to which the Company pays taxes, maintenance, insurance and certain other operating expenses applicable to the leased property. The Company expects that, in the normal course of business, such operating leases that expire will be renewed or replaced by other leases, or the property may be purchased rather than leased. The following table summarizes future minimum rental payments primarily related to aircraft required under operating leases that had initial or remaining non-cancelable lease terms as of June 30, 2018 (in thousands):
