Planning a complicated Europe multi-city itinerary used to be a nightmare, but Google Flights handled it in minutes and the explore map showed me cheaper nearby airports I'd never considered. The filters for layover length and number of stops are exactly what I needed.
Excellent multi-city and explore tools
I tracked a Mumbai to Singapore route for three weeks and Google Flights emailed me the moment the fare dropped by 6,000 rupees. The map view and flexible date grid let me shift my trip by a day and save even more. Nothing else I've used surfaces deals this clearly.
Price tracking alerts and flexible date view
Google Flights makes comparing fares across airlines genuinely effortless and the price calendar saved me a chunk on a Delhi to London trip. My only gripe is that it doesn't actually book the ticket, so you still get bounced to the airline or an agent to pay.
Fast, clear price comparison
No direct booking
Found a great fare on Google Flights but when it sent me to the airline site the price was nearly 40 dollars higher with no explanation. It happened on two separate searches the same evening, which made the whole comparison feel pointless.
Quoted fare didn't hold on the airline site
I love the interface but Google Flights missed a low-cost regional carrier that was clearly cheaper for my Bangalore to Goa hop. Because I trusted the comparison, I almost overpaid until a friend pointed it out. It needs to be upfront that not every airline is included.
Misses some low-cost carriers
