Gates change constantly. Agree with **Procrustus **that big Delta and small Delta Express gates will be in two separate groups. You might get lucky and have each gate be near the border with the other group. But that’s not the way to bet.
When you print your boarding passes for both legs at home the night before or at the first airport the morning of, take note of what gate it says for departing from SLC. That’s tentative information, but *much *more stable than anything you’d learn any farther ahead.
It would be worth checking via Delta’s website before your turn off your phone after boarding the flight to SLC. I don’t know if Delta provides connecting gate info on board during arrival or not. It probably depends on how new your inbound airplane is. But they might. We do on the planes with fancy enough datalinks and entertainment systems.
Either way, Job #0 as you deplane checking is checking immediately via the flight info screens around the terminal or the agent greeting the flight.
Though all it can give you is historical data, you can check your flight #s in Flightaware.com to see what gates have been used for them. It’s a start, but I fear Delta is setting you up for a frantic rush when they could simply have put you on in earlier flight into SLC from your origin airport (BWI, right?).
Looks like there is only one flight per day from SLC to WYS and it’s on Delta. If you miss your connection, you are going to be stuck in Salt lake until the following day.
Driving time is just under 5 hours. So you could have a back up plan to rent a car and drive to West Yellowstone, so that you don’t lose a whole day of your vacation.
Ivylad wanted to ask a question, so he logged onto Delta with our itinerary info and there was a notice that due to flight changes, we may not make a connection (the time between SLC and WYS had changed to about 25 minutes).
We called and got an earlier flight from MCO to ATL and from ATL to SLC, which gets us into SLC with about two hours to spare before our WYS flight.
A few years ago my wife and I flew to New Zealand and back. I didn’t notice something till a few day before our return flight, we only had about 45 minutes between the flight from Auckland to San Francisco and San Francisco to Seattle. I assumed it would be as smooth as the other way, no security and the 2 airlines transferring our luggage. Not.
Upon landing we found out we had to collect our luggage from Air New Zealand and deliver it to United. Which meant leaving the security zone. Plus we had to get new boarding passes. Plus we had to go through customs. Except for the boarding passes, everything went smooth and we made our flight in plenty of time.
Have a wonderful trip.
