With little sign of the pressure abating, it isn't hard to imagine the airline's investors -- not to its mention social media team -- breaking a sweat.
Update 3:31 p.m.: Munoz issued a second statement on Tuesday afternoon, this time heartily apologizing for the incident, which he called a "horrific event," and calling for a "thorough review" of company procedures. Read his full statement below, via USA Today:
The truly horrific event that occurred on this flight has elicited many responses from all of us: outrage, anger, disappointment. I share all of those sentiments, and one above all: my deepest apologies for what happened. Like you, I continue to be disturbed by what happened on this flight and I deeply apologize to the customer forcibly removed and to all the customers aboard. No one should ever be mistreated this way.
I want you to know that we take full responsibility and we will work to make it right.
