Boeing 773 Thai Airways
We were looking very much forwards to fly back home after 6 month in Thailand with the brand new Boeing 777-300er, but we were extremly disapointed because of very large noice from the engines and less legroom compared with the Boeing 747-400 they have always used for this flight. In over 10 years we have each year been flying with Thai Airways to Thailand with the 747. But now we consider to change Airline because we are not at all happy with the 777-300

A Thai Airways Boeing 777-300, registration HS-TKL performing flight TG-970 from Bangkok (Thailand) to Zurich (Switzerland) with 339 passengers and 20 crew, was accelerating for takeoff from Bangkok's runway 01L when the crew rejected takeoff at low speed (about 55 knots over ground) due to the failure of the left hand engine (GE90). The aircraft slowed safely and returned to the apron. The left engine shows a large hole at the inboard casing.
The airline reported the aircraft was taking off from Bangkok when the left hand engine failed prompting the crew to reject takeoff. It was found the aircraft needs repair, no spare aircraft was immediately available, hence the passengers were taken to hotels. A replacement aircraft departed later the day.
A replacement Boeing 777-300 registration HS-TKK reached Zurich with a delay of 12 hours.
Late Oct 23rd 2019 the FAA released Emergency Airworthiness directive EAD-2019-21-51 stating the EAD was prompted by 'by an event that occurred on October 20, 2019, in which a Boeing Model 777-300ER airplane powered by GE GE90-115B model turbofan engines experienced an uncontained high-pressure turbine (HPT) failure that resulted in an aborted takeoff. Debris impacted the aircraft fuselage and the other engine. Uncontained HPT failure, if not addressed, could result in release of high-energy debris, damage to the engine, damage to the airplane, and possible loss of the airplane.' The EAD requires operators of GE90-115B engines with certain engine serial numbers to remove from service the Interstage Seal, part number 2505M72P01 with serial numbers GWN0TCL3, NCE062LD, NCE254LC, NCE314KU, NCE374LB, NCE527KT, NCE777LD, or NCE994KW within 25 cycles based on the GE Alert Service Bulletin GE90-100 S/B 72-A0826, dated October 23, 2019.
