CORRECTION at the end of the text.
I applied for the card, received it promptly, started to use it physically at various merchants as well as on amazon.com without any issue.
I had a trans-Pacific BC ticket to purchase, so I went to cititravel.com, which had issues, so it took a while to start the booking process.
When I tried to purchase the selected ticket, I got an error message and was asked to call the phone number on the back of the card.
I spent the 90 mns on the phone, spoke to several representatives but received the same error message after re-creating the ticket (for every unsuccessful attempt, you receive an email from cititravel and a booking #, which gives you access to the itineray of the ticket that you tried to book, but this cannot be used when you attempt to pay for the ticket again) and tried to pay for it.
The Citi customer service represensatives, except one, were not helpful. The one that was more willing to help, called Cititravel and stayed over 30 mns on the phone waiting for somebody to pick up the phone, but we agreed that we were going nowhere and staopped the call.
The next day, I tried again and was transferred to the Citi Fraud Dept., which was very unprofessional and unefficient. I even spoke to a supervisor of that dept., which transferred me to Cititravel without asking me or telling me that she will hang up and let me deal with the Cititravel agent.
The Cititravel had my booking on his screeen after I gave him the # (I accessed to Cititravel after logging in the Citi website). He asked me a LOT of questions, but I stopped answering after he asked me for my social security #. I stopped the booking process at that point as I cannot remember a travel agent asking for sec. soc. #.
I called Citi and cancelled my card with an agent that was very apologetic.
