If the reality of business trip expenses doesn’t match the budget, hidden travel costs could be the culprit. Flight delays and rescheduled meetings can derail your team’s travel plans, with rebooking adding unplanned expenses to the original budget. Unexpected baggage fees, hotel service charges, and international roaming charges can all chip away at the best-planned travel budget, leaving your department scrambling to make up the difference.

Part of corporate travel planning is understanding the little hidden fees. The travel industry is notorious for add-on service charges, not to mention the added costs of telecommunications and taxes. In this article, we’ll give you a rundown of the most common categories of hidden travel costs to prevent any surprises. This will help you plan your average business travel expenses more accurately for better resource allocation.

Airline baggage fees

Gone are the days when an airline ticket quote covered all costs. It’s easy to get confused by airline baggage rules, even for seasoned corporate travel planners.

This is because airline baggage rules change frequently and aren’t always stated clearly at the time of booking. While most international flights include a free checked bag and carry-on, you can’t count on it. For domestic flights, you’ll almost certainly have to pay baggage fees for anything that doesn’t fit under the seat or in an overhead bin.

Excess baggage fees can run between $19 and $100, or more depending on size, so make sure you know what’s included.

What are hidden airline fees?

In addition to excess baggage fees, hidden airline fees sometimes include extras like priority boarding, extra legroom, and in-flight Wifi. Many now charge for meals and drinks. As you’re creating a business travel budget for your team, work all these little costs into the total price of airfare.

Third-party booking fees

Some booking platforms charge to make your flight, hotel, and rental car reservations. While these may be incorporated into the total ticket price shown, they’re sometimes added at the end as a separate charge.

The best way to avoid these hidden booking fees is by using a business travel management solution like Booking.com for Business that doesn’t charge any subscription or booking fees. In addition, companies benefit from exclusive corporate rates on flights, hotels, and car rentals. With flexible booking options, you can also avoid unexpected cancellation fees.

Hotel service charges

Hotels make up a high percentage of average business travel expenses, so you’ll want to examine fees carefully when budgeting.

When you’re quoted a per-night cost, it may only cover the room itself. Some hotels charge additional fees for use of their onsite facilities like a fitness center, spa, or swimming pool.

Additional hotel service charges might include things like:

  • Housekeeping fees
  • Concierge fees
  • Laundry charges
  • Parking fees
  • Luggage storage
  • Early check-in or check-out

What are hotel incidental fees?

If you see “incidentals” listed on a hotel invoice or receipt, this refers to extra amenities used during a hotel guest’s stay. This includes things like:

  • Room service
  • Minibar
  • On-demand entertainment
  • Phone calls

Notably, most companies don’t include these incidentals as a valid work travel expense, so business travelers will need to pay these hidden travel costs out of pocket. When you’re crafting a company travel policy for your team, specify which incidentals are covered and which travelers are expected to pay for.

Parking charges

Whether business travelers take park-and-ride public transportation to an all-day convention or use a secure hotel garage, it’ll probably come at a cost. This isn’t necessarily a hidden fee, but it might come as a surprise if you assume free parking is included with accommodations.

International roaming charges

Does the company phone package include international roaming charges? If not, your finance department could be in for an expensive phone bill. One study found that US businesses pay up to $693.50 in international roaming charges per employee, per overseas business trip. In Europe, companies spend an estimated $3 billion per year on roaming costs.

Roaming charges may apply to each minute and megabyte of phone use, and with business travelers required to stay connected, this really adds up.

Wifi access fees

Wifi is readily available in most public areas, including airports, train stations, and hotels. But, it’s not always free. Access passes in public areas could cost $12 to $19 extra per day.

Foreign transaction costs

When business travelers use a credit or debit card overseas, they could be charged a foreign transaction fee. This varies by card issuer and financial institution, but typically costs anywhere from 1% to 3% of the total transaction value. While that may not seem like a lot, imagine that a team member is allocated $1,000 on their company card for a business trip. At a rate of 1%, this would cost an additional $10 in transaction fees, and at 3%, that goes up to an extra $30.

VAT rates and taxes

Taxes are one of those hidden travel costs that get left out of the budget. Chief among these for travelers is VAT, or value-added tax. These rates depend on the country you’re traveling in and its tax regulations, ranging up to 20% of the total cost of food, lodging, and transit. In most cases, the company can reclaim this VAT if it was used for business trip expenses, but this isn’t always the case.

Sales tax—added to retail goods—is another hidden cost that ramps up total expenditure while traveling.

Cancellations and delays

Whether due to weather or mechanical issues, flights get delayed and hotel bookings get canceled. Business travel insurance is always a good idea to cover the cost of cancellations and delays, but this comes with its own added cost.

If your company has had a schedule change that requires rebooking, note that cancellation fees vary widely by supplier. Always read the terms and conditions before booking and choose flexible travel options where possible.

Why should you watch out for these hidden costs?

Corporate travel is big business worldwide, costing companies billions. In China, the total annual spend on business-related tourism was $372.5 billion, while the United States spent $361.6 billion and the UK spent $51.5 billion.

With this post-pandemic rebound effect, the travel industry is taking full advantage. Costs of flights have soared as airlines try to recoup lost profits, and demand is high. All this means that businesses need to keep an eye on travel budgets more than ever, particularly SMEs that may be working with tighter margins. Every penny counts. All these seemingly small hidden costs add up to put strain on your budget.

Tips for reducing hidden travel costs

Awareness of things like excess baggage charges and hotel service fees is the first step toward avoiding them. Follow our tips to reduce hidden travel costs and bring down your business trip expenses:

  1. Pack lightly: Avoid those costly excess baggage charges by encouraging business travelers to only carry what they need, and take time to read the airline baggage rules.
  2. Join loyalty programs: Airline-issued credit cards and loyalty programs often waive excess baggage fees and offer free priority boarding.
  3. Plan ahead: Book early to take advantage of better group deals on flights and accommodations, with more availability and choice. Use trip planning apps like Hopper or TripIt for maximum efficiency.
  4. Monitor expenses: Use expense-tracking apps to spot trends, monitor business payments, and identify areas where you could save.
  5. Read the fine print: Do your research before booking a hotel. Find out what’s included in the price, or whether you’ll have to pay extra for Wifi, breakfast, and parking. This will let you compare prices more accurately.
  6. Purchase a prepaid data plan: Avoid international roaming charges and extra Wifi costs by purchasing a data plan before you go. Consult your company’s mobile service provider to see what’s available, and consider investing in local SIM cards for corporate travelers.
  7. Use a fee-free card for travel: Some of the best business travel cards come without added foreign transaction fees, including options from major banks.
  8. Use a travel management system: If your company has a business travel booking tool, it may allow you to bypass those added third-party booking fees. Platforms like Booking.com for Business also feature exclusive rates on corporate car rentals, flights, and hotels so you know you’re getting the best deals.

What’s the biggest travel expense for businesses?

Business travel expenses encompass any purchases made by employees while traveling for work. As such, the biggest expenses are dependent on your team’s itinerary. When employees fly long haul in first class for a weekend event, transportation could be the biggest travel expense. For business trips closer to home, accommodations tend to be the biggest work travel expense.

Apart from flights and accommodations, additional business travel expenses to work into your financial planning include:

  • Car rental costs
  • Train tickets
  • Public transportation costs
  • Taxi fares
  • Meals
  • Client entertainment costs
  • Conference registration fees
  • Visa fees
  • Mobile phone charges

What’s the most expensive day to travel?

According to research, Sunday is the most expensive day of the week to fly. This is because of all the weekend travelers heading home, increasing demand. Days before and after major holidays like Christmas and New Year’s Eve also spike transportation costs.

Keep average business travel expenses under control

When forecasting business travel expenditure, factor all these extra charges into your budget to avoid costly surprises.

Flight cancellations, last-minute bookings, and hotel service charges can quickly inflate even the most meticulously planned budget. Awareness of the most common hidden costs is the first step in managing travel budgets and keeping expenses from spiraling out of control.
