What constitutes being able to go for Hajj?

The definition of being able to go for Hajj is: a person should be physically healthy; he should have the means of travelling to the Sacred House of Allah by plane, car or riding-beast, or have the money to pay for transportation; and he should have sufficient provision (food) for the journey there and back. This should be over and above what he needs to cover the costs of expenses for those whom he is obliged to spend on until he comes back from his Hajj. A woman should also be accompanied by her husband or a Mahram when she travels for Hajj or ‘Umrah.
