I will be spending a week in Greece, arriving in Athens, then will head to Santorini for a few days and return back to Athens for the remainder days. I was planning to go by plane to Santorini, after my flight to Athens which will be at least a 2 hr layover, using Aegean Airlines, but I'm having trouble booking with their website with debit card errors. I called my bank and they say my card is fine and I also booked an Athens hotel using the same card online with no problem.
My concern is after reading reviews and horror stories of using Aegean I'm a bit nervous now to use them (if I can even book!). My other option would be a different airline with similar bad reviews or the ferry which even the fast one can take almost 5 hours. Are there any suggestions on the best way to get to Santorini? Should I just go with Aegean? (Despite the mixed reviews).
