Recently, I was booked on a flight on EasyJet between two European capitals. I had a ticket allowing me for one bag of max 20 kg. However, when my bag was weighted at the check-in counter, it weighted 20.9 kg but (to my surprise) the lady at the counter told me it was "ok".
So my question: is there a "tolerated" amount of weight exceed (for example max + 1kg above the upper limit) or was this only a matter of chance that I didn't have to pay a fee for the exceeding weight (ie 900 g)?
This question concerns EasyJet in particular but it would be interesting to know if similar can be applied to other airlines.
