DO NOT BOOK WITH THIS TERRIBLE COMPANY. Don't do it. As a solo female traveler, I wanted a more "reliable and secure" experience going from the airport to my hotel since I'd heard some things about taxis in Paris. Well, little did I know this company is way worse than that and reliable and secure are not something they know the meaning of. First of all, they make you select a flight from their drop down menu, so if their information is incorrect, what you submit will be incorrect. My flight information was incorrect in their system and so they sent me an email requesting I update it or else "my transfer might be cancelled". First of all, regardless if my flight info is wrong, if I book a transfer for pick up at a certain date and time, the driver SHOULD be there and wait their 30 minutes. That's what I PAID for. I "update" the information and this time the flight is correct in their system and they reply with an email confirming the update. Great, all is good then. Then after my 11 hour flight I check my email since there is no WiFi on my flight and I see a ton of emails from WelcomeTransfer and my driver saying the information is wrong and my transfer has been cancelled. I had also messaged the assigned driver and the "great, friendly, warm driver (they claim to have)" didn't even respond to my message, so that's how great they are. They are claiming I submitted incorrect information regarding my flight which again, was not incorrect and only offered an 80% refund even though THEY cancelled it based on their fraudulent terms. I've already told them to refund me the full amount since I provided everything correct and they are the ones who for some reason decided to cancel my transfer or I'll do a chargeback and they can deal with proving how what I provided was incorrect. Don't ever use this shady company. Also, my taxi experience from ORLY was great and way cheaper than this hack of a company, so just do that instead!
