Q: I will be leaving for Umrah in a week. I will be landing in Jeddah, and I will have to be in the state of Ihram. I have a few questions regarding going into Ihraam. 

1. I will make the ghusul in South Africa that morning before I leave for Jeddah. Will it be valid if I go into Ihraam on the plane before landing in Jeddah?

If I go in to Ihraam on the plane must I make the the 2 rakaats of Sunnat Salaah on the plane.

2. As mentioned in question 1, if I go into Ihraam on the plane, must I proceed straight to perform Umrah or I may go to the Hotel?

3. As mentioned question 2, if I can go to the hotel and then perform Umrah, can I remove the Ihraam I was in and make ghusal and re-enter in to Ihraam?
