[QUOTE=Jeanske_SN]What aircraft has fuel for flying in a hold for two hours?[QUOTE]

If you are within weight limits there’s nothing to stop you from taking whatever fuel you need to hold. If low vis procedures are in force (Cat 2 or 3) we are supposed to plan to arrive with an absolute minimum of 45 minutes holding fuel bur can up that figure as much as we wish. It would be silly to fly half way round the world and then divert for the sake of a few tonnes of fuel when you knew the weather was going to be pants.
