Commit acts of kindness and it will come back ten fold
Something wonderful in the concept of karma, isn't there?
A smile and a kind gesture go a long, long way after what can sometimes be a bit of an ordeal, referring to air travel that is.
Seems to be a shift in the vibration all over the last few days/weeks. One can only hope it translates to air travellers as well.
All you can really do is smile, smile, smile... and hope it catches on.
