I ordered 2 tickets to fly via Allegiant airlines via Esky. I never received confirmation via email. There is NO phone number to contact them. They never replied to single email. My credit card flagged transaction as possibly fraudulent but then confirmed charges were legit. Luckily, I was able to deal directly with Allegiant (honest broker in the deal) to confirm I had tickets, confirmation of flight and they supplied boarding passes. Other than credit card transaction, I never had not even one email from Esky. No confirmation, no boarding passes, NOTHING! Allegiant states Esky is 3rd party broker and while legit company, they do not recommend them.If there had been any need to change or refund flight, I'm sure that would have been impossible with just a loss of my money. Buyer beware, do not use this company!
