That all sounds good though I would recommend Naxos over Mykonos in March as there’s more to see and do there when not beach weather. And if you do decide to do Mykonos be sure there’s a ferry from Mykonos to Santorini for your dates. And same for Santorini to Crete. There should be ferry service but the route starts different times every year so you do want to be certain.
They are packaged tourist places, though not quite in the extreme league of the north coast of Crete, but certainly they look to the ‘managed’ traveller more than the individual. September is a good time, though the start of September is still pretty close to high season and you will need to make bookings in advance. The waters of the Ionian are a bit chillier than the Aegean, but the islands sport some very spectacular beaches and seaside resorts. They are very popular with Italian travellers in their boats and motorhomes.
Ultimately, the federal government provided $4.6 billion in one-time, subject-to-income-tax cash payments to 427 U.S. air carriers, with no provision for repayment, essentially a gift from the taxpayers. (Passenger carriers operating scheduled service received approximately $4 billion, subject to tax.) In addition, the ATSB approved loan guarantees to six airlines totaling approximately $1.6 billion. Data from the U.S. Treasury Department show that the government recouped the $1.6 billion and a profit of $339 million from the fees, interest and purchase of discounted airline stock associated with loan guarantees.
