Dear me QPH. You must be joking? TT has mostly been a 'loss leader. It has only made a profit a couple of times. It has lost more than it has made. It is a loss-maker at nett. For FY19 it was negative EBITDAR. It was essentially bankrupt. It is able to operate because of VA. Be assured - TT is not 'propping up' VA. VA domestic is a cash cow. It is what keeps the VA group functioning as an airline. TT financials have improved now mostly due to reducing cost through less aircraft and obliterated head office labour force. This naturally will increase unit revenue and yield, as they've announced. Also understand that the 'first half' is the 'good half'. The second half is where everything gets very ugly. Being handed clapped out (and paid down) B737's will dramatically reduce the cost base for TT as the lease expense for the 320's exits, and there will be for sure - synergies for maintenance, systems etc...
And you have to look at cashflow. Don't get caught up in 'underlying' and 'statutory' profits so much. Free cash is king!
