I wish journalists would stop simply reprinting intentionally misleading company spin like this without any attempt to refute it. Fuel costs are one of the least sticky price increases imaginable and are already decreasing after they peaked last once. Plus no one knows what inflation will be like in a year. There is nothing close to permanent about these cost increases.
The most charitable interpretation of these comments is that past increases were only because of permanent issues and this new surcharge represents a change in that policy. However if that is the case, this comment should more clearly denote that change and explain why this temporary increase is different and requires a change in policy.
