I work for an airline that does this regularly.
As long as Solomon Airlines remains an entity, and continues to sell tickets, it will be liable, through IATA, to repay its debt.
Solomon Airlines is the Airline, Strategic is supplying the aircraft, (the charter), this is the way we have done it for years, and have never been stiffed. And that's in places, with airlines that are a lot less reliable than IE. (they do exist).
