Hi -
Even if they only save $.05 to $.10 per package by swapping in pretzels for biscoff, that is $10-$20 per flight. Even at the lower end, over the course of a year, that starts to add up.
The reality is that doing stagflationary times (and we are only 1/3 through this current one in my estimation), with costs rising faster than GDP growth in the service sector, the only alternative is to trim expenses anywhere possible. You wil see this across all sectors of the economy.. In Business Class, the amenity kits get cheapened. Champagne becomes Sparkling wine. French Red becomes Chilean Red. All while the cost of the ticket has climbed at least 50%.
I make the same travel calculus. I used to fly Alaska up and down the West Coast. Now I fly Frontier. I used to Uber everywhere. Now I take public transportation when feasible.
