The Google Flights search service has been updated with a new ‘tips’ feature that’s designed to surface cheaper flights. Tips is designed for those with some flexibility in their schedule, as sometimes the cheaper flights are a day before or after the preferred flight date or time. But if you’re on a budget, the feature will be very helpful to maintain finances – and it reveals whether a different nearby airport is offering a non-stop alternative flight to your destination, and even cheap upgrades to business class. Google Flights also includes a ‘best flights’ section that shows flights that are probably the best trade-off between price and convenience.
