Many of us are, most of the time, choosing planes flights as our mode of transportation, mostly when we are traveling abroad. Holidays, visiting friends and relatives, many people even having jobs in another states. We got many of options in companies, we can always choose the cheapest flight in our date and book it. But the problem is not only with searching for correct flight. Also, we have to get ready to our journey, and beaware of many ordinances about flying by jet. Another thing is luggage, at the very first time we are booking our tickets, we need to choose type of it.
