I haven’t heard that the airlines have removed the surcharges they added when fuel prices spiked.
Nor has UPS. One of my favorite pet peeves....Like going into a restaurant and paying a 'plate surcharge'.
It took them decades to do it, but the airlines have finally aligned capacity with demand, and firmed up prices. I remember in the 90s flying on a lot of half full planes, that never happens anymore. Then again with $2/gal, more folks will drive.
