Booking a flight from NYC to Las Vegas, and CO gave me a price of 2153NOK for my chosen flight, which is $391 with the current exchange rate. I've always booked flights in my own currency, as CO always recognizes my country when I go to their site. For some reason I decided to check the prices if I chose USA as my country, and sure enough - price for the same flight was $318. So I thought I'd just book it and choose the right country later, but then I get this: "We’re sorry, but you must begin your search again in order to purchase this reservation with a form of payment in your billing address country. Please click on the Search button below to begin your search again." So I managed to work around it by opening another tab and logging in to my OnePass, and then hitting "back"-button on the tab with the error message. This enabled me to stay on the US-site while my correct Norwegian details were filled out. So now I'm wondering if CO has been discriminating against me and charging me extra all this time, or have they just not bothered changing their exchange rates for the last two years?
