Applications to find cheap flights and lodgings

Google Flights is integrated into the search engine and offers a detail of the best flight prices on different airlines. Enter "flight" and the name of the destination to receive a listing. Then the search can be adjusted based on the number of stops, the airline, the date, etc.

Travel it a meta-search engine for flights and hotels also offers price comparison for the different routes you want to make.

Recently they added a new filter that allows the user to know what type of luggage is included in the price.

I am considering that many airlines offer very cheap flights but only if the passenger carries a small carry on and does not dispatch luggage.
