Sadly, not a website, but some random checks from yours truly.
Y fares for the itinerary below were £30 cheaper.
However, penalties for amending, changing seem to be much steeper on DL.
Booking PE looks a nightmare on DL, as they don't have an equivalent service, However, you can choose to book by class, and Delta helpfully shows "Premium Economy" above the price.
Business offers no such hassles...!
