United Airlines CEO Oscar Munoz has reportedly suffered a heart attack.
The recently appointed airline CEO suffered the heart attack within the last 24 hours and is currently in a Chicago-area hospital, the Wall Street Journal is reporting, citing people familiar with the matter.
According to the report, United Airlines board members are awaiting news of the severity of the heart attack to determine whether an interim CEO will be required.
Munoz joined United Airlines as its president and CEO in September after former chief executive Jeff Smisek resigned as a result of a federal corruption investigation.
Prior to joining United, Munoz served as president and COO of CSX Corporation — a freight transportation company.
