Pretty sure Delta from Tor to Atl to SXM will mean a plane change in Atlanta. The Tor flight is probably a Canadair flight, maybe a 717 - Atl to SXM will be a 737 / 757 depending on the flight chosen.
We've looked at those options to save money, but for our time slots the savings have not been much, not enough to entice us away from a non stop from Tor to SXM [less than $100 CDN per ticket]
The OP seemed to get a great price though, so it's always timing of when to buy!
