I am trying to book a ticket from ATL to MXP on the website - I am given NO options of doing the TA leg first, then connect to MXP (like CDG to MXP) - almost options are going first to JFK. Does DL have designated / set flight paths for certain European destinations? The options are totally different for ATL to VCE however the cheapest on these use Air France - the Delta flights are hundreds more?! Will I have more options as it gets closer to travel time?
