Can we take a bag 190lcm weighing 30kg? if so what will the excess charge be?
That depends on the company which you are flying with. Every air company has an website with bagage regulations and mostly the prices for extra lugage
Nobody can answer this question with the missing info
I agree. Depends on the airline, whether there are other bags and your total allowance will be exceeded and so on. You have not really given any detail.
Many airlines will quote their excess baggage rates on their websites. Its often cheaper to pay for oversize/overweight baggage in advance, than turning up with at the time of check in, on a 'suck it and see' basis.Edited: 16 May 2018, 04:09
