This tool began as a master itinerary planner. You email them your itineraries from multiple sources (hotel, airline, restaurant, etc.) and it puts them together into a trip plan. This function is strong even if some small details (like sending a subsequent updated itinerary may lead to two of the same flight showing on the same date, which you then have to manually edit) can be trying. The other strong function is the points tracker, which is informative but not as critical as the trip planning tool. However, other functions sound good on paper but don’t have the usefulness a discerning traveler requires. Take the seat tracker for example. If you book a premium economy seat on BA and want to search for an outside aisle seat, you can search for aisle seats in front of the wing, behind the wing, or anywhere. This cabin can be both on and behind the wing so there’s no way to narrow the search appropriately. And if you want a premium economy cabin seat, you have to add the cabin to economy rather than say you want only premium economy. If you want an outside aisle seat (not a middle aisle), forget it - that’s not an option. So this app is the epitome of good intentions poorly delivered. But still worth using if you don’t expect too much.
