Carry-on vs personal item is a question of size and storage. A personal item is the smaller bag that must fit under the seat in front of you, and a carry-on is the larger bag that rides in the overhead bin. Each airline sets the dimensions for both, and your fare decides whether you get one of each.

The best time to book flights is not a fixed day or week. It is the moment a fare on your own route fits both your budget and your plans. Demand for that flight, the seats left at each fare level, the season, holidays, school breaks and local events all move the number.
The 24-hour flight cancellation rule is a federal requirement in 14 CFR 259.5. When you buy a ticket directly from an airline at least seven days before departure, the airline must either refund you in full if you cancel within 24 hours or hold the quoted price for a day. Travel agency bookings sit outside it.
In the basic economy vs main cabin choice, both fares usually seat you in the same economy cabin; the rules are what differ. Basic economy usually gives up seat choice, changes, upgrades and an early boarding group, and on some airlines a full-size carry-on. Main cabin usually keeps those options open. Rules vary by airline.
A missed connecting flight on a single ticket is normally the airline's problem to fix: it rebooks you on a later departure at no new fare. On separate tickets the second airline owes you nothing. Head for the transfer desk and the airline app at once, and keep every boarding pass and receipt.
How to find cheap flights comes down to a repeatable routine rather than a trick. Fix the parts of the trip that cannot move, widen the dates and airports you would accept, compare one ticket against separate tickets, read what each fare includes, and check the full total before you pay.
There is no federal rule for how early to arrive at the airport. Airlines typically advise about two hours before a domestic flight and about three hours before an international one, and TSA says the right time varies by airport and by date. Check your own airline and airport, because cut-off times vary.
This international flight booking guide sets the order. Confirm every traveler's passport and the entry rules for each country on the route, then choose the route and connections, then compare fare rules and baggage. Book last, read the e-ticket against each passport, and recheck the rules before you fly.
