Despite continuing efficiency improvements from the major aircraft manufacturers, the expanding demand for global air travel has resulted in growing greenhouse gas (GHG) emissions. Currently, the aviation sector, including US domestic and global international travel, make approximately 1.6 percent of global anthropogenic GHG emissions per annum. North America accounts for nearly 40 percent of the world's GHG emissions from aviation fuel use.[79]
Hi Dave! Your website is so detailed and helpful! I’m starting to plan a trip for late May-early June. We were interested in visiting Santorini, Naxos (we opted for Naxos instead of party-filled Mykonos) and Milos. Our main airport of arrival is Athens. What order should we visit all three islands (in terms of convenience of ferry/flight availability) and how many nights do you recommend allotting to each? Thanks in advance for your time!
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.)[49] 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.[50]
