FAQ (Frequently Asked Questions)

一、自分にぴったりのスーツケースを見つけよう

When planning a trip, one of the first important items to consider is a suitcase . Knowing what type of suitcase is suitable for your travel style and duration is the first step to making your trip smoother and more comfortable. So, what points should you pay attention to when choosing one?

1. 「泊数」だけで決めて大丈夫？知っておきたいサイズ選びのコツ

When choosing a suitcase, do you just decide based on the number of nights you'll be staying, such as "S size for one night" or "L size for a week"? Actually, there's another important thing to check.

That is, to comply with the rules of the airline you are using .

・The size difference between domestic and international flights is surprising!

On most domestic and international flights in Japan, carry-on luggage is permitted as long as the total of its three dimensions is within 115cm (e.g., 55 x 40 x 25cm). New Trip's small size bag is also designed to meet this standard.

・[Example] The small but big difference between "55cm" and "50cm"

One thing to be aware of here is that some international airlines, such as Qatar Airways, have a height restriction of 50cm or less . If your bag is the standard Japanese size S (approximately 54-55cm), even a difference of just a few centimeters could mean you have to check it in.

In addition, some airlines, such as Lufthansa, require a slimmer design, with a maximum thickness of 23cm .

  • If you are on a route with strict height restrictions: A smart way to avoid panicking at the airport is to not try to carry it on, but to use it as checked luggage from the start.

2. 「本体の軽さ」をチェックして、もっと自由にパッキング！

Just as important, or perhaps even more important, is the weight of the suitcase itself .

Especially when using low-cost carriers (LCCs), the total weight of carry-on luggage is often limited to 7kg .

・"The suitcase itself is light," so you can pack one more souvenir.

If the suitcase itself weighs 3.5 kg, then you only have 3.5 kg of luggage left inside.

This means that just putting in a change of clothes and toiletries will put you right at the limit.

On the other hand, if you choose a lightweight model with a body weight of around 2.8 kg , such as New Trip's 0201 or 0701plus , you will have more space inside.

・"You can carry another pair of your favorite clothes without worrying about the weight."

・"You can buy the wonderful souvenirs you find on your trip without having to hold back."

The lightness of the body directly translates into "freedom of travel."

・Safe even for LCCs! Why lightweight models are recommended

Recently, airports are increasingly using automatic weighing machines to strictly check luggage down to the 100g mark. The first step in packing is to choose a lightweight model from the start, so you don't have to panic at the counter thinking, "If only it was just a little lighter..."

Free yourself from the stress of weight and enjoy your trip with more ease!

3. 旅の「困った」を解決してくれる、便利な機能を使いこなそう

Suitcases have many different functions, but the important thing is whether they suit your travel style.

We will introduce recommended features for common travel situations.

If you travel by train or bus a lot: with a stopper (1101 model)

The wheels can be locked with a single switch at your feet.

Your suitcase won't roll around even when the car is shaking, so you'll feel much less tired while traveling.

・If you want to quickly take out your laptop at the airport: Front-opening (0501 model)

You can easily open the front pocket while the suitcase is standing upright.

The great thing about this bag is that you can easily take out your PC or small items at security checkpoints or cafes.

・If you think you might have more luggage on the way home: Expanded function (0502 model)

Simply open the zipper to expand the gusset and increase the capacity.

This function fulfills the selfish desire to travel compactly on the way there and bring plenty of souvenirs on the way back.

二、適切な旅行バックパックの選び方

A backpack is one of the most important items when traveling. Especially when you'll be carrying your luggage for long periods of time, the backpack you choose will have a big impact on your travel comfort. By choosing the right backpack for your travel purpose and style, you can reduce the burden on your travels and improve the ease of accessing and carrying your luggage.

So, let's take a look at what to look for when choosing the perfect backpack for travel.

1. スーツケースと「合体」できるものを選ぼう

Our top recommendation is a backpack with a carry-on function (handle loop) on the back. This allows you to attach the backpack to the handle of your suitcase while traveling, eliminating any strain on your shoulders. This is especially useful for long trips through the airport or while waiting at the station.

2. 貴重品を守る「隠しポケット」があると安心

When traveling, it's important to keep your wallet, passport, and other valuables safe. A backpack with a hidden pocket on the side that touches your back makes it impossible to reach inside while wearing it, greatly increasing security.

3. PCやタブレットは専用ポケットへ

If you're carrying gadgets, choose a bag with a dedicated, padded pocket. This is smart because you won't have to worry about them hitting other items and you can quickly access them at airport security.

三、旅行アクセサリー：空港での「困った」を未然に防ぐ

Travel accessories are essential for comfort, organization, and safety during your trip. Just like the main items like suitcases and backpacks, travel accessories play an important role in making your trip more convenient and enjoyable.

Here we will introduce travel accessories that are essential for travelers and explain how to choose each one.

1. デジタルはかり：追加料金の心配をゼロに

Checking your luggage at the airport counter can be surprisingly stressful. With a palm-sized digital scale , you can quickly check the weight before leaving the hotel. This one item gives you peace of mind when it comes to the 7kg limit on low-cost carriers or when your luggage is heavy on the way home because of souvenirs.

2. 晴雨兼用折りたたみ傘：どんな天気でも身軽に観光

Sudden rain while traveling or traveling on a sunny day can take a toll on your energy.

New Trip's all-weather umbrella is incredibly lightweight and compact. Simply slip it into the side pocket of your suitcase or backpack and you can enjoy walking around town without worrying about the weather.

3. キャスターカバー：部屋を汚さない新習慣

When you walk on the road outside, the casters inevitably get dirty and covered in fine sand. By attaching special caster covers (wheel covers), you can carry your luggage without dirtying the floor of a hotel or your home. This is a secretly popular item that eliminates the need to wipe down the wheels after you get home.

FAQ（よくある質問）

Q1. 機内持ち込みできるスーツケースのサイズ規定は？

A1：2026年現在、基本は「3辺合計115cm以内」ですが、海外航空会社（カタール航空など）では「高さ50cm以内」という厳しい独自ルールがある場合も。 New TripのSサイズは標準規定をクリアしていますが、行き先が決まったら高さ制限もあわせて確認しておくと安心です。

Q2. LCCの「7kg制限」をクリアするコツは？

A2：「本体の軽さ」を最優先に選ぶことです。本体が3kgを超えると中身がほとんど入りません。 New Trip 0201のような2kg台の軽量モデルを選び、パッキングの自由度を確保しましょう。デジタルはかりで事前に重さを測っておくのも失敗しないコツです。

Q3. 電車やバス移動が多い場合、おすすめの機能は？

A3：勝手に転がっていかない「キャスターストッパー機能」が必須です。 New Trip 0301ならスイッチひとつで車輪を固定できるので、揺れる車内でも手で押さえ続ける必要がなく、移動の疲れが劇的に変わります。

Q4. 拡張機能付きは機内持ち込みしても大丈夫？

A4：ファスナーを閉じた状態（非拡張時）なら機内持ち込みOKです。 行きはコンパクトに持ち込み、帰りにお土産が増えたら拡張して「預け入れ」に切り替える。New Trip 0201なら、そんな柔軟な使い分けが可能です。

Q5. 旅先での雨や日差しへの対策はどうすれば？

A5：軽量な「晴雨兼用折りたたみ傘」を常備するのがスマート。 New Tripの傘はコンパクトで場所を取らず、急な雨だけでなく強い日差しもカット。どんな天気でもアクティブに観光を楽しむための必須アクセサリーです。

Q6. 海外のホテルで床を汚さない方法はありますか？

A6：専用の「キャスターカバー」が非常に役立ちます。 外を歩いた車輪にカバーを被せれば、土足文化の海外でもホテルの床や自宅のフローリングを汚さずに済みます。帰宅後の車輪掃除の手間も省ける、隠れた人気アイテムです。
