I booked my ticket 3 days back in Main Cabin (V class) but I am not able to pick any seats in comfort+. As late as this year, there was a check box at the bottom of the booking page to request upgrade to comfort+. I do not see that either. Has their been a change to Delta policy to no more allow upgrade from Main cabin to comfort+ on Delta international flights? This is for a flight on 30th January.
thanks for responding.
