United Airlines faces financial losses as a result of Boeing jet grounding.

United Airlines, the largest US carrier of Boeing 737 Max 9 jets, has announced that it is expecting to incur losses in the first quarter of the year. This comes as a result of the Federal Aviation Administration's (FAA) decision to ground 171 of these aircraft after an incident where an unused door detached during a flight. United Airlines currently has 79 of these planes in its fleet, followed by Alaska Airlines. Both airlines have had to cancel numerous flights as inspections are being carried out. United Airlines has stated that it anticipates the planes to remain grounded until January 26, assuming they won't be able to fly them at all this month. The FAA has further stated that an older model, the 737-900ER, should also undergo inspections as it shares a similar door design. United Airlines has 136 of these planes in its fleet. The FAA emphasized that the safety of passengers is their priority, and not hastening the re-entry of the affected planes into service. Boeing has expressed its commitment to enhancing inspection procedures in response to the incident. United Airlines is expected to provide updates on safety inspections during an upcoming call with analysts and investors, while both Alaska Airlines and Boeing are set to report their results in the coming weeks.
