We were planning a multi-city tour. And it was hard to get flights arriving in a state and then departing in another.
After lots of blogs and google search, I found good reviews about Google Flights. It enabled me to find flights for our multi-city destination. It also tracked the cheapest flight based on my required time and date. I tried it again this time just to show and inputted random airports and dates.
Once satisfied, it led me to a link and asked me to either save the flights or book it. I was checking different flights and airline combinations per day and saving it before I was fully satisfied that I was getting the cheapest.
Once done, it directed me to the airline website. At the airline site, all my chosen date and time, and cities were already there. Then that’s it! All that is left is to fill in the credit card details! :)
