Bad day indeed.
I land with Final Reserve, but without Alternate fuel - is this still legal?
Im quite sure it is.your alternate can be changed while enroute if it complies with the alternate weather minima specified by your regulator/airline.
If you arrive at x airport with multiple runways/approach aid in CAVOK,this airport can be used as your new alternate,hence landing with min reserve is ok but far from being recommended.
Reserve fuel is indeed for your alternate,a way out but also for last resort contigency fuel,,,go around.
I would not like being in a position where arriving with min reserve fuel and knowing a go aroung will leave me 10 mins of fuel onboard.
Keep your reserve as much as you can,know your rules but dont abuse them.
