Overcoming the Problem
I looked into ways of grouping all of these confirmations, and one common factor they all had was that they all send a confirmation email. I’ve been grouping my trip confirmation emails within Gmail too, which helps, but there is a lot of extra fluff apart from just the details I need, which can make searching difficult.
Another issue is that even if you do use Gmail labels, it requires data to access them, which isn’t always immediately available when you want it when travelling, and it can use quite a lot of (roaming) data when having to access the images and attachments.
Looking deeper into the problem, yet another issue that I encountered is that when travelling in a group we will split the bookings, and therefore split the payments between us, but that means that we all each only have some of the emails for the trip. Whilst we will forward them to each other, and I’ll still use the groups in Gmail, it doesn’t make it easy to navigate – it throws out the real sender, the date etc.
