Know what a flight is really like before you book it. See real passenger reviews by route: which flights are always late, which planes are old and cramped, which crews are great, and which airlines hit you with surprise fees.
After landing, leave a review in seconds: star rating, a photo, and a short opinion. No long forms.
The more people review a route, the clearer the patterns get, for the next passenger and for the crews who deserve credit.
