I wouldn't hold my breath for Delta to permanently REMOVE peanuts from their inflight snack service: Delta is Atlanta, Georgia based. Peanuts are big cash crop & heavy lobby influence out of Georgia.
It seems, however, that Delta has decided to make some policy change that may be positive and helpful for some in the PA community. For those of us fortunate to have a REAL CHOICE as to which airlines we can and will fly, well . . . there are still the options of airlines who CEASED all peanut service more than a decade ago, e.g United , among others. For those of us travelling with small children and/or level of reaction such that heavy residue on surfaces and in the plane's air system might be a problem, travelling on these other airlines where aircraft aren't filled with peanuts except for the accommodating flight -- the ZERO-peanuts-service airline -- is often the best and/or ONLY option.
And, well, hot-damn if the Delta crews and employees were actually INFORMED and HELPFUL and
ACCOMMODATING !!
THAT is big change from Delta, IMHO.
Big!
