Here is something interesting.
Transport Canada (Aviation) a few years ago removed the requirement from the regs to carry "route reserve" fuel to or from Mexico and the Caribbean.
Now add to this the airline that operates a 'plane at max ZFW and can only take so much fuel so as not to exceed MTOW. Send it to Mexico with no reserve fuel, to airports that have only one runway and no parallel taxiway (that could be used in an emergency) with the closest alternate 100 miles away. To a country where comm is not always the best. A place that is earthquake prone (damaged runways).
Listen to the dispatcher tell you "it's a legal flight plan fuel load" when you ask about the lack of "reserve" fuel.
Why does the industry work against the very people (pilots) who keep it alive ?????
The Captain is NOT always in a position to take the fuel he/she would like to have and the regulators are NOT on the side of the pilot when they remove such an important requirement from the regs. U.K. regs are one thing and Canadian regs are another.
