Example deadlines are: 6 [4] to 72[3] hours. The earliest acceptable timing is not mentioned, but merely checking-in the previous part of the trip does not count as a reconfirmation for the latter part. If the traveller fails to reconfirm their flight reservation, the airline may cancel it.[3] This also means that if the traveller is forcefully deboarded ("involuntary deboarding", or "bumping", in jargon) from a flight because of the airline's overbooking, the traveller can not receive the standard compensation.[6]
