At online check-in my Turkish Goldness shone through, and the free allowance of one checked bag was clearly highlighted.
Out of spite the system gave me a seat in the centre of the second last row (TP doesn't give any choice at check-in, unless you pay). This unthinkable slight was remedied by the gate agent, who slotted me into an empty row 6: still behind the curtain, but there's (said to be) extra legroom and other seat-related thrills.
I picked up a EUR10 voucher which was fine for a sandwich and a drink to take with me on board.
