ITA Airlines - Unable to book flight between Rome and Athens. Should I book Sky Express?

Have you tried just calling them to book by phone?

Yes, I had that same problem a week ago. I rebooted computer and then it worked.

Are you using a VPN? If yes, you can try connecting to another server from your VPN or simply disconnect from your VPN to make the transaction. You may also need to clear your cache of cookies. I have this happen fairly frequently when using my VPN.

Thank you to everyone's' suggestions.

I have rebooted; no luck.

Changed VPN locations; no joy.

Turned off VPN; did not work.

May reboot router and see what happens...and may try calling as suggested.

At what point in the process do you get that message?

I just did a dummy booking and got to the payment page without a problem. Didn't enter any credit card info, so if the problem is in the final step, I have no clue of any other suggestion.

(Using firefox on a Dell laptop)

I downloaded Firefox on our Dell desktop-same message.

I would try rebooting our router, but our son is doing on-line school work for his final semester in college. I obviously do not want to hinder that in any way...

Hubby is currently listening to some horribly-cheesy "hold" music, on speakerphone, with ITA...

*edited to add more info...
Depending on what I am using - desktop-if I click from google flights to ITA, that is where I receive the message. This is in Chrome.

In Firefox, when I enter ITA and click on their website, that is where I receive the message.

On my iPad, linked to my phone and cellular - not my home wifi, I can get all the way through to purchase, but when I click "Continue" the continue button does not work.

Last Update

Husband was able to talk to ITA and their phone customer service was fantastic!

We have booked our flights, have tickets, names are correct on the tickets and the tickets show up in the ITA app; so hopefully things will go well on travel day.

Thank you again to everyone for your help.

Glad it worked out!!

I am getting the same message today. Right after I enter flight dates.
does not inspire confidence, May have to go with KLM

I had trouble booking with them about two years ago. I called them and did speak with an agent, in Albania. But I was anxious about making the booking by phone, and ended up booking the same flights with Delta. Ii think, though, that I was overcautious and Delta fares were higher.

Question: If you booked by phone, was there a fee involved? it seems like phone is the way to go if anyone has problems on their site (as I did back then, even after trying several browsers)

I just looked at my receipts and there was no fee. I really prefer booking online-when all the tech is running smoothly of course, but making the reservations by phone was very easy. I am reluctant to give out card information over the phone, but so far, no noticeable issues.

Thank you!!
