We did it last year. 90 mins would not have been enough time for us. Took us 2 hours to get through immigration and customs. Delta was ok to fly with no problems there. Just be aware if there are any problems you are on your own to sort out as it’s an American airline. We had a nightmare last year as got to Detroit and then found out our flight from Detroit to Orlando was cancelled and was offered a flight two days later. Which wouldn’t of been too bad but it was a two stop flight and they didn’t offer us a hotel.
I ended up booking flights with another airline called spirit airlines cost us £450 extra but it was worth not hanging around for two days! Especially for kids. Just my opinion. I won’t do that route again.
