LATAM Airlines specifics: Light fares: no overhead bin access (personal item only). Economy (other): 1 carry-on + 1 personal item + 1 checked bag.
A cabin bag is included, but on the cheapest fare at LATAM Airlines the hold allowance is "Not included (Light)" — you pay 1 bag included for the first checked bag. Only 4 of the 24 airlines here charge for the cabin bag itself, so LATAM Airlines is not one of the worst offenders.
Most major international airlines accept 55×40×23 cm (22×16×9 in) as their carry-on limit. If your bag fits these dimensions, it will be accepted on almost every airline worldwide.

Exception: Budget carriers like Ryanair (40×20×25 cm personal item, larger bag costs extra) and Spirit/Frontier (18×14×8 in free item) have smaller free limits.
Always add bags at booking, not at the gate
Gate-added bags on budget carriers (Ryanair, Spirit, Frontier) are 2–4× more expensive. Add online — it's cheaper, and sometimes dramatically so.
Carry-on 'size' is rarely enforced on all airlines
Major US carriers rarely measure carry-ons unless bins are full. Budget European carriers (Ryanair, Wizz) sometimes use metal gauge testers — especially on popular routes.
Weigh your bag before you go
A simple luggage scale ($8–12) pays for itself the first time you avoid an overweight fee. Hotels usually have scales if you're worried at checkout.
Overweight/oversize fees can exceed your ticket price
Spirit overweight fees are $100. Ryanair: €11/kg at the gate. Pack within limits — redistribute to carry-on if close to the limit.
Codeshare flights: use the operating carrier's rules
If you book on United but fly Lufthansa, Lufthansa's baggage rules apply. Always check the operating carrier — logos on your boarding pass clarify this.
Credit cards can give you free checked bags
Airlines co-branded credit cards (Delta Amex, United Explorer, Southwest Rapid Rewards) typically include 1–2 free checked bags per flight for the cardholder + companions.
Liquids rule: 100ml / 3.4oz per container in a 1L bag
Applies at every major airport worldwide (TSA, EU airports, Australian airports). Any liquids over 100ml must go in checked bags — no exceptions at security.
Medication goes in carry-on, not checked bags
Checked bags occasionally get lost. All prescription medication, especially refrigerated items, should travel in your carry-on with original prescription labels.
Oversize bag
Most airlines define oversize as a bag where the total linear dimensions (L+W+H) exceed 62 inches / 158 cm. This applies to most checked luggage. A typical large suitcase (29 in) is 78 linear inches — oversize on almost every airline.
Overweight bag
Standard checked bag limit is 23 kg (50 lbs) for economy. 51–70 lbs (23–32 kg): typically $100–200 fee. 71–100 lbs (32–45 kg): $200–400. Over 100 lbs: not accepted as checked baggage on most airlines.
