Here is my last trip:

Leg 1...left eng won't start. Eng fuel valve. RTB. Mechanic resets fuel handle, signs off write up. push back again. left eng still won't start. Eng fuel valve. no parts in Denver. flight cancels. dh to layover.

leg 2...pack temp controller deferred but timed out! Mechanics fix pack temp controller. 2 hr delay. finally board, cater. NO FUEL. CSR asks "you got everything?". Capt. replies "no, we need about 40 THOUSAND pounds of gas". Another 40 minutes before we push. 3 hrs + late.
