well flying back JFK-LHR-DUB with about 5 hrs in LHR before continuing on...the agent affixed the first sticker to the bag but the second agent (two of them working the stand as it was a very slow night) was told by the first agent she forgot to affix the SHORT transfer tags. so the whole re-print and all to affix both tags.
i laughed to myself that it didnt seem 5hr layover is SHORT but i figured maybe that would be better than nothing haha.
