Input: Passage: Yesterday I made a flight reservation to fly from Boston to Chicago . The first step in making a flight reservation is to determine which airline you would like to fly . I picked American Airlines because I have most of my airline miles with them and I always like to earn more miles . The website then provided me a bunch of different flight options for both my departing and returning flights . I selected the flights that worked the best for me and were the most affordable and I selected them . I was then directed to pay for my flight which I did via my American Airlines credit card . I find that using the internet is much easier than calling the airlines for a flight reservation . Question: When did they enter the desired dates of their flight? Option1: after opening the American Airlines website Option2: after paying for the flight
Output:
after opening the American Airlines website
