Here is an example. SEA - PSC (Pasco, WA). Growth, still excellent load factors.

Several years before Covid:

8 daily at 37 seat turboprops. = 296 seats

Today:

2 daily at 76 seat RJ = 152 seats
3 daily at 178 seat 737-900 = 534 seats
Total = 152+534 = 686 seats

Real upgauging. More seats, fewer pilots.
