[2026 Latest] ANA New Regulations & LCC-Compliant Suitcase Size Selection Guide!

Title

The most common regrets people have when choosing a suitcase are, "It was too big at the airport" or "My souvenirs didn't fit on the way back." Specifically, from May 19, 2026, ANA's domestic flight regulations will be updated, clearly defining the maximum free baggage allowance as a total of 158cm in all three dimensions. The 203cm standard, which was previously permitted on some domestic flights, will effectively be discontinued, and the international standard of 158cm will become the new norm.

 

This guide, based on New Trip's actual measurement data, explains everything from how to choose the optimal size based on the number of nights, to the latest airline regulations, including those of LCCs.

First, refer to the quick reference table below to find the size that suits your travel style.

一、ANA新規定でスーツケースサイズはどう変わった？

A basic guideline for choosing suitcase capacity is "10 liters per night," but it's safer to choose a slightly larger size when considering bulky winter clothing or souvenirs for the return trip.

Below, we will introduce the optimal capacity for each number of nights and recommended models based on New Trip's actual measurements.

項目 旧ルール 新ルール
預け入れサイズ 3辺合計203cm以内 3辺合計158cm以内
適用路線 国内線 国内線・国際線
重量（エコノミー） 23kg以内 23kg以内（変更なし）
重量（ビジネス） 32kg以内 32kg以内（変更なし）

*Sizes are measured including casters and handles.

*The information in this article is as of July 2026.

ANA's regulations may change, so please always check the latest information on the ANA official website.

・預け入れサイズが203cm→158cmに厳格化

This is the most popular "all-around size" for domestic travel and short-haul international trips to places like Korea and Taiwan.

Its greatest feature is that it's carry-on compatible. You don't need to check it in, which reduces waiting time at the airport, making it ideal for business trips and quick getaways.

However, if you're flying with an LCC, "weight" becomes the biggest hurdle. Airlines like Jetstar and Spring Japan have a limit of 7kg total for the suitcase itself plus personal belongings. If the case itself is heavy, you won't be able to pack much.

二、ANA機内持ち込み・身の回り品サイズを確認

Baggage rules vary significantly between airlines and routes.

In particular,ANA domestic flights from May 19, 2026 onwardswill undergo significant changes, so please be sure to check the rules before choosing your luggage size.

Key Points (ANA domestic checked baggage from May 19, 2026)

  • Size: Total dimensions (length + width + height) within 158cm (including casters and handles) → This is a significant tightening from the previous 203cm limit. If measured over at an automatic baggage drop-off machine, there is a high possibility of incurring an additional fee (approximately 5,500 yen).
  • Weight: For Economy Class, up to 23kg per bag is free (32kg for Premium Class).
  • Number of items: For Economy Class, generally up to 2 bags (may be 1 bag depending on the fare type).

・For details, please also refer to ANA's official website:Information on automatic baggage drop-off machines.


 

For carry-on baggage (ANA/JAL wide-body aircraft)

  • Total dimensions within 115cm (目安: 55cm × 40cm × 25cm)
  • Total weight for carry-on baggage + personal items is within 10kg

For LCCs (Peach, Jetstar, etc.)

  • Many flights have a strict carry-on weight limit of within 7kg.
  • Since adding checked baggage incurs an extra fee, it is recommended to choose a lightweight suitcase.

Advice from New Trip
All suitcases handled by our store comply with ANA's new 2026 regulations (within 158cm) in actual measurements including casters and handles. However, some models may exceed the limit if checked with the expansion fully extended, so we recommend measuring the size before your return flight if you anticipate buying many souvenirs.

・機内持ち込み手荷物（頭上棚収納）

機材 サイズ制限 3辺合計
100席以上 55×40×25cm以内 115cm以内
100席未満 45×35×20cm以内 100cm以内

・身の回り品（前の座席下収納）

As of July 1, 2026, new size restrictions for personal items have been implemented.

  • Size: Within 40 x 30 x 20 cm
  • Weight: Total of 10 kg or less, including your carry-on baggage

When choosing a carry-on suitcase, please ensure it meets the size regulations for "carry-on baggage" that can be placed in the overhead compartment (within 115 cm).

三、ANA旅行の日数別｜おすすめスーツケース容量の目安

Once you have an idea of the size, the next step is to choose features based on "how you will use it," which will reduce the chances of making a mistake. This is because even for the same size, usability can vary considerably depending on the features. Especially when considering ANA's new regulations (within 158cm), choosing the right features becomes even more important.

旅行日数 目安容量 おすすめサイズ ANA預け入れ可否
1〜3泊 30〜50L Sサイズ ◎問題なし
4〜7泊 50〜80L Mサイズ ◎問題なし
7泊以上 80〜100L Lサイズ △3辺合計158cm以内を要確認

If you tend to accumulate souvenirs when returning home, or if you're going on a trip where the amount of luggage is hard to predict, a suitcase with an expansion feature is convenient.  

However, when expanded, the total dimensions will increase, so please be sure to choose one with ANA's 158cm standard in mind.

Most of the expandable New Trip models are designed to be well within 158cm even before expansion, so you can use them with peace of mind.

Title

四、ANA新ルール後に失敗しないスーツケース選びのポイント

・Lサイズは3辺合計158cm以内を確認する

L-size items are most affected by the new rules.

Always check the "total of 3 sides" value listed on the product page.

It is also important whether the dimensions include casters and handles.

・軽量モデルなら重量制限に余裕が生まれる

The checked baggage weight limit for economy class is 23 kg.

The lighter the suitcase itself, the more luggage you can pack.

For example, if the suitcase weighs 3 kg, you can pack 20 kg of belongings, but if it weighs 5 kg, you can only pack up to 18 kg. If you plan to buy many souvenirs, we recommend choosing a lightweight model.

・お土産が増えやすい旅行には拡張機能付きを

When traveling abroad, you often accumulate more souvenirs on the way back.

With an expandable model, you can keep it compact on the way there and increase its capacity with a single zipper on the way back.

However, please check that the total linear dimensions do not exceed 158cm when expanded.

・長時間移動にはキャスター性能も重要

When flying with ANA, where there's a long distance from the airport to the train and then to the hotel,

choosing quiet casters will make your journey more comfortable.
