https://transtats.bts.gov/Data_Elements_Financial.aspx https://transtats.bts.gov/Data_Elements_Financial.aspx shows 2001-2005 net income losses were 57 billion dollars, then a brief profitability in 2006-7 but the losses of 2008 and 2009 wiped that all out again (in net income terms). I read that thing about the integral of all profits back to the Wright Brothers back around in 2010, and I can't find a good source on aviation profitability in the 1970's right now.
