My flight to London is delayed due to a technical issue with the aircraft. The airline is being vague about the resolution time, and I'm concerned about safety.

A significant component or system within the aircraft has malfunctioned, requiring immediate and potentially complex repairs or replacement. The airline may be hesitant to disclose specifics due to proprietary information or to avoid causing panic.

The necessary replacement part for the technical issue is not readily available at the airport and is being shipped from elsewhere. This can lead to unpredictable delays.

The technical issue may have triggered a mandatory inspection or review by aviation authorities or internal maintenance oversight, which can add significant time to the resolution process.

The airline might be intentionally vague to manage passenger expectations, avoid liability, or because they genuinely lack concrete information and are still assessing the situation.
