Had an interesting booking experience earlier today. Booking a last minute one way to New York for later tonight. Called reservations since I wasn't at a computer and asked for the lowest fare to any of the New York airports. Was quoted a price of $176 and thought I got lucky but then the confirmation came and I saw that it was a tango fare. A class. Thought it was weird so called back AC and agent was confused at first as well. After putting me on hold for a few minutes she came back on the line and told me that they have started experimenting with low price last minute Tango fares transborder as of today. Just my luck. For the curious, the Tango Plus fare was almost double at $325
