All (proper) Airlines have a simple solution for that, they just turn off GPS. Most of the time the ADIRS/ADIRU (bit too much to explain what it is here, the Wiki article is pretty good) does it automatically as well.
For those interested, here’s a Video where GPS gets jammed and there’s an explanation on what they do and what happens, when it gets spoofed https://www.youtube.com/watch?v=4dG_Whxzdkk
With the inertial reference navigation, they’re not accurate enough for approaches like RNAV aren’t really viable.
Some airports only have this as the instrument approach option with complex way points without radio navaids, and as such the flight may need to perform a visual approach or divert if jammed during the approach phase.
In short, it’s not as bad as people might think, but can cause some problems.

Yes, and also they have VOR/DME and ADF.
