Two updates from the Times of Israel:
Also see another article describing this unexpected 'alliance' between Saudi Arabia and the U.S. This development is so interesting for a variety of reasons (see comments below article):
When US Secretary of State John Kerry made another stop in the Middle East this month, he received an expected earful over Washington’s outreach to Iran: Don’t trust Tehran, tighten sanctions even more, anything short of complete nuclear concessions is a grave mistake.
Kerry’s meeting wasn’t in Israel, though. It was with in Riyadh, listening to Saudi leaders.
In one of the region’s oddest pairings, Israel and the Gulf Arab states led by Saudi Arabia increasingly are finding common ground — and a common political language — on their mutual dismay over Iran’s history-making overtures to Washington and the prospect of a nuclear deal in Geneva that could curb Tehran’s atomic program but leave the main elements intact, such as uranium enrichment.
Uzi Dayan, a former Israeli deputy chief of staff and national security adviser, said Israel is singled out as the main alarmist over Iran’s nuclear program, but the Sunni Arabs in the Gulf, Egypt and elsewhere are just as galvanized in opposition.
This bolded statement is quite interesting. With Egypt's military/government trying to purge the country of the Muslim Brotherhood, and aligning with Israel over the border and the ongoing problem with terrorist groups, it would be easy to see Egypt covertly allowing Israel to fly over their airspace in route to Iran. We have already seen at least one article speculating on a similar arrangement in which the Saudis would allow Israel to fly over their country for an attack on Iran's nuclear facilities.
The route to Iran has always been listed as a big problem in terms of an Israeli attack on Iran's nuclear facilities. Recent developments may have solved that problem. You can see from the map what a big difference the use of Saudi Arabia would be for these flights to Iran.
