I'm flying TLV -> LHR this week and have substantially more baggage than usual this time around. I'm flying PE which includes 2 x 23 kg bags, OneWorld Emerald which adds another, plus I'm adding a fourth at an eye-watering $170(!) so 4 x 23 bags in total.

I'll weigh my bags before I go, but let's assume my scales are inaccurate (reasonable) and the bags turn up at 23.5 kg each. Are BA likely to impose an overweight fee? Is there an unwritten tolerance?

I know this has been discussed before, but the answers are inconclusive and I'd be interested to hear if anything has changed.

I made a big mistake buying a couple of massive Samsonite hard shell cases just for this trip. I thought I got a great deal second hand but turns out that with the 23kg weight limit, one can't utilise even 80% of the space unless one is packing feathers...
