Thai Airways International (TG, Bangkok Suvarnabhumi) has yet to reach an agreement with Airbus (AIB, Toulouse Blagnac) and Boeing (BOE, Washington National) over the planned deferral of deliveries for fourteen aircraft including twelve A350-900s and two B787-9s airline president Charumporn Jotikasthira has said.

Speaking to Reuters, Charumporn said that in the event Thai is unable to reach an agreement with the manufacturers, it would still abide by the terms of its respective sales contracts.

"Financially we don't need the planes and commercially we have not sold enough tickets. The more capacity we have the more trouble we will run into, so the more we can delay the better," he said.

In January, Charumporn alluded to negotiations with the two manufacturers over revised 2018 delivery dates for the aircraft deemed surplus to requirements.

Thai is scheduled to take delivery of its first two A350-900s later this year with the type set to make its commercial debut on July 1 with a daily Bangkok Suvarnabhumi-Melbourne Tullamarine return service. Thereafter, five A350s will arrive in 2017 followed by a further five in 2018.
