Flight from Milan to New York and back in the same week and got incosistent treatment between the two flights.Flew with only cabin baggage to New York and got confirmation that it was compliant with their policy: assistant in Milan put also the "cabin allowed tag" on my suitcase.When checking in at JFK, ground staff forced me instead to send the same bag, still having the tag from Milan.Reason? My purse was the 1 piece allowed carry on bag.Wouldn't mind if it was not an expensive suitcase, carrying fragile stuff...and if in the boarding queue I wouldn't spot many people with 2 cabin baggages.Thnks to ground supervisor Pranavi Rana for the zero flexibility, zero empathy and the blind application of an inconsistent policy.
