Any aircraft lease agreement is strictly non-refundable and non-amendable. While this option may reflect preferential pricing, the lease is final upon verbal or written confirmation and may not be cancelled, modified, or rescheduled for any reason, including but not limited to changes in dates, routing, or aircraft type. No refunds, credits, or adjustments will be provided in the event of cancellation or requested changes. These terms are established and enforced by the aircraft operator and are not subject to negotiation or alteration by any intermediary or third party. Only ECA management may modify this policy.
