Jews changing planes in Arab countries? How does this work?

This weekend, several news stories were published about various Arab oil countries buying dozens of new planes – B-777, B-787, and so forth, so that they can diversify their economies by building major air traffic hubs in their respective countries. Dubai, Qatar, the UAE, and Saudi Arabia were among the ones mentioned.

None of those countries have much love for Jews and (if I remember correctly) Saudi Arabia doesn’t even let them in. Especially if there is an Israeli stamp on a passport.

Now suppose Dubai gets a huge air hub going and a Jewish person is flying from Beijing to Johannesberg for business. The person has to change planes in Dubai.

Can that person even land in Dubai (or Saudi, or whatever soil)? Can that person leave the airport and stay in a hotel? Take a tour? Etc.? What are the effects on a Jewish air traveler changing planes in an Arab country?
