We are planning to fly delta. From spokane wa to sna orange county. Prefer to fly through SEATAC . The cheapest tickets for our dates had a mere 1hr 7min layover in Seattle. Main cabin fair and traveling with 5 people in total. This is just a connecting flight, not going through tsa or anything.

I fear this is too short after hearing from others there are 5 hr delays on tarmac at seattle for every flight, flights itsself says an hr but ive seen 1.5 hr flight so thats alread an issue. Ive been told most often you have to take train from one end of terminal to other which takes 30mins , plus boarding being half hr before takeoff.... that leaves 7 mins by my math to get off plane from spokane and be at gate to depart.
delta said its totally enough time and never have delays on tarmac ... and theyd move you next flight if you missed it anyway... next flight is the next day even though this is a morning flight.

So I just want to know.. are people telling me right about seatac itself and taking forever to get across or is delta correct that's its enough time?
