Have you been to either of those? The old SLC was kinda tight in the final years, but it was designed for '50s traffic. The new one is pretty big and spacious. ABQ is a small/mid-size airport, it’s not big, but it also doesn’t handle too many passengers so space isn’t a huge problem.
Does your airport have an amazing hotel? A museum with tons of cool planes near it? Lots of rare planes you won’t see anywhere else? Actually comfortable terminals?
I didn’t realize that SLC gets arrivals from all of their long haul destinations tomorrow:
AMS-SLC DL A339
CDG-SLC DL A339
FRA-SLC 4Y A333
LHR-SLC DL A332
AMS-SLC KL B789
