Esky reviews

What a lie: I've been waiting for a response for several days!

Same problem, I tried the contact form and all the variants eSky.fr, eSky.eu, eSky.com and still no confirmation email. Not a single booking reference. It is absolutely necessary to note the reference at the time of purchase. The bank transaction is pending. Ticket purchased 2 days ago for a flight in 2 days.
According to various forums, they use a proxy email address to book with the airline. So, it's impossible to find a confirmation in my name on the airline's site which requires the email used. I will try to contact the airline which has a toll-free number for existing bookings.
If they still have nothing, I will consider blocking the bank transaction and booking directly with the airline.

@AurelieFrThe airline gave me the booking number and I was able to access the reservation directly on their website. I noticed that the reservation has changed from pending payment to confirmed. I added the baggage directly on the airline's website as I still haven't heard from eSky. Not a single confirmation email or even the invoice.

@AurelieFrOne must read reviews before booking on an unknown site; here, it is clearly a mafia site that takes reservations even for non-existent flights. Thousands of people have been deceived, and yet this mafia can still be found on sites like Kayak.

@Didier79Personally, I always book directly through the airlines because in case of issues at the airport, they have a counter or someone on-site or a reachable phone number for low-cost airlines.
I helped someone who isn't used to technology and took the first website with the attractive price. In the end, it saved €25 compared to the airline's website directly, but it cost 2 days of stress.
The savings were only possible because with WizzAir, you can access the booking directly on their site with the booking ID (which the Existing Booking service from WizzAir provided me) and the last name (no need for the famous agency email). I was able to add baggage from the WizzAir site with WizzPriority for €18 instead of €25 to €50 for baggage at the airport and download the boarding pass from the site as well; otherwise, it costs €35 at the airport.
If I hadn't called WizzAir for access to the booking, the person would have gone to the airport not knowing if they had a seat on the plane and would have ended up paying €60 or more at the check-in counter.

eSky does the minimum, so if it's for a one-way or round trip without baggage or options, the flight is minimally booked, so even if people don't hear from them, they have a seat on the plane.
But it's too risky to go through them because at the slightest problem, change, canceled flight, or options or baggage, there's no one left, and since low-cost airlines charge everything at high prices at the airport (boarding pass, baggage, seating...), it can quickly add up.

For info on rates, the starting price for this flight was €235 on WizzAir's public site, the person paid €209 for their ticket on eSky, and at the time of connecting to the reservation on the WizzAir site, the booking was pending payment confirmation for an amount of €64.
