So stressful waiting for the real story to come out. I've been planning this trip for months, and all of the restrictions and changes that have happened up to now have not affected my itinerary, other than differences in paperwork and scheduling tests, etc. Somehow I ordered my destinations perfectly so as to avoid problems, and if I had reversed legs I would have had issues! I'm going MIA-LHR-(AUH-DXB - immediate xfer)-IST-NAV-IST-BCN-MAD-MIA. BCN/MAD could be impacted by whatever comes out in the next few days. Leaving 6 Sep. Am reading up on CAI as a possible alternative to BCN/MAD. Would like to keep my MAD-MIA flight, so transit rules will also be particularly important if I end up not entering Spain.
