Did a CO 738 (DFW-)IAH-POS-IAH(-DAL) round-trip this weekend. Several miscellaneous comments: - CO flew <30% load factors on the Trinidad flight. Are they making money on this flight? - What are two (Canadian) RCMP Pilarus (?) aircraft doing in a hanger at Piarco? - CO seats are abysmal. I simply don't fit. Be thankful I am in the only one in my row. - While CO serves food (on it's international), it's on the low-end of edible. I'd rather pay $5 and get a decent meal - The "Flight plan" on the screen (for) apparently isn't driven by GPS. The F/A announced that she had to "program in Caracas because Trinidad wasn't available. Don't be alarmed" (On the map we were heading WEST from Trinidad over Venezuela on the map, even though we were nearly over Grenada; which is north.) - IAH wasn't planned, it just happened. Matthew
