Travel and Dysphagia
For many elderly patients with dysphagia and their caregivers, travel can feel impossible. But with careful preparation, the right kit and a flexible approach to meals, short trips (such as the Greater Bay Area) and even longer journeys (Southeast Asia, Japan, the UK) are achievable.
This guide helps caregivers plan systematically, manage food-related challenges along the way, and handle the unexpected.
Important: Before any trip, confirm with the patient’s SLP that swallowing function is stable, and obtain a written diet prescription in both Chinese and English. Patients with unstable swallowing or a recent aspiration event should consult their doctor before travelling.

Travelling with Thickener: Regulations and Tips
Airline Rules
Thickener powder (such as xanthan gum-based thickener) is generally permitted in carry-on baggage and is not subject to the 100 ml liquid restriction. However, some airports may flag powder for additional screening.
Recommendations:
- Carry the SLP diet prescription in English as proof of medical necessity
- Place powder in a clear sealed bag to facilitate security checks
- Pre-mixed thickened drinks in carry-on baggage are subject to the 100 ml liquid limit — it is more practical to purchase a drink after security and mix thickener at the gate or on board
Carrying Large Quantities
For longer trips, bulk thickener should travel in checked baggage. Recommended:
- Keep the original packaging with instructions intact
- Before departure, identify whether pharmacies at the destination stock the same or a similar product
Airport Dining at Hong Kong International Airport
HKIA offers many dining options, but IDDSI-compatible choices require active selection.
Suitable choices at HKIA:
- Congee (available at multiple Chinese restaurants in both terminals — request strained, no solid toppings)
- Steamed egg dessert
- Steamed egg savoury dishes (available at some outlets)
Avoid:
- Fast food (burgers, fries)
- Sushi and sashimi
- Whole fruit with skin (apples, pears)
Lounge access: If the patient has access to an airline lounge, many offer hot food including congee and soups, providing more suitable options than terminal restaurants.
Eating on the Aircraft
Booking Special Meals
Most international airlines offer pre-ordered special meals. Relevant options for dysphagia:
| Meal Code | Name | Suitability |
|---|---|---|
| BLML | Bland Liquid Meal | Suitable for patients requiring liquid-only diet |
| MOML | Muslim Meal (soft version) | Sometimes softer than standard meals — enquire with airline |
| VLML | Vegetarian Liquid Meal | Suitable for patients requiring liquid diet |
Important: Airline special meals are not prepared to IDDSI standards. Caregivers must still verify food texture on board and modify as needed.
Common In-flight Food Options
| Food | IDDSI Suitability | Handling Notes |
|---|---|---|
| Oatmeal (porridge) | Level 4–5 | Confirm no hard oat pieces |
| Yogurt | Level 4 | Remove any fruit pieces |
| Pudding / cheesecake | Level 4–5 (varies) | Avoid varieties with jelly pieces |
| Cream soup | Level 3–4 | Thicken; confirm no solid pieces |
| Clear broth/consommé | Level 0 | Must be thickened |
| Soft bread roll | Level 6 | Moisten thoroughly; avoid crusty varieties |
Drinks on Board
All standard aircraft beverages (water, juice, tea, coffee) are thin liquids (Level 0). For patients prescribed thickened drinks:
- Ask the crew for a cup of water, then add your own thickener
- Inform the crew of the medical need — they typically assist readily
- Avoid carbonated drinks
Choosing Wisely at Hotel Buffet Breakfasts
Hotel buffets offer wide choice but variable texture — caregivers must actively verify everything served to the patient.
Safer Buffet Breakfast Choices
| Food | IDDSI Level Reference | Notes |
|---|---|---|
| Cooked oatmeal (soft) | Level 4–5 | Confirm no hard oat grains |
| Softly scrambled eggs | Level 5–6 | Avoid overcooked, rubbery eggs |
| Steamed egg (if available) | Level 4 | |
| Greek yogurt (plain) | Level 4 | Remove honey or solid fruit toppings |
| Ripe soft banana (mashed) | Level 5–6 | Mash before serving |
| Ripe avocado | Level 4–5 | High-energy natural soft food |
| Cream soup | Level 3–4 | Thicken; confirm no solid pieces |
Foods to Avoid or Handle with Care at Breakfast
- Whole fruits with skin (apples, pears, oranges)
- Toast (hard crust), bagels
- Bacon, over-cooked sausages
- Muesli or granola (mixed texture, chewy dried fruit)
- Jam with whole fruit pieces
Travel Within the Greater Bay Area (Guangdong Province, Macau)
The GBA shares Hong Kong’s Cantonese food culture, making it relatively accessible for dysphagia caregivers.
Advantages:
- Congee is widely available at Cantonese restaurants in Guangdong
- Cantonese (or Mandarin) can be used to communicate dietary requirements directly
- Higher-end hotels in Guangzhou and Macau offer English service
Challenges:
- Casino buffets in Macau have highly variable food textures — caregivers must actively screen everything
- Congee in some Cantonese restaurants can be very thin (near Level 0) and may need thickening
- Pharmacies in mainland China may not stock Hong Kong commercial thickener brands
Emergency backup: In Guangdong province, corn starch (玉米澱粉) is available in supermarkets for temporary use, but consistency is far less stable than commercial thickeners — avoid long-term reliance.
International Travel (Japan, Southeast Asia, UK/Europe)
Japan
- Silken tofu (嫩豆腐 / 絹豆腐) is an excellent Level 4 option, widely available
- Chawanmushi (steamed savoury egg custard) can be ordered at izakayas and set meal restaurants
- Tororo (grated mountain yam) has a naturally thick, cohesive texture suitable at around Level 4
- Japanese thickener brands (とろみ剤) are sold at pharmacy chains — re-verify dosing, as concentration may differ from Hong Kong brands
Southeast Asia (Thailand, Vietnam, etc.)
- Congee options (Thai Jok, Vietnamese Cháo) are widely available — strain solids before serving
- Egg drop soups and tofu soups are suitable with thickening added
- Commercial thickeners are rarely available locally — bring sufficient supply from Hong Kong
UK / Australia / Canada
- Porridge (oatmeal) is a standard breakfast option at Level 4–5
- Commercial thickeners including Thick-It and Nutilis are available at Boots (UK), Woolworths and pharmacies (Australia), and Shoppers Drug Mart (Canada)
- IDDSI is widely adopted in the UK, Australia and Canada — healthcare professionals are generally familiar with the framework, making communication easier
Managing Emergencies During Travel
Thickener Supply Exhausted
- First assess whether a local pharmacy carries an equivalent commercial thickener
- In an emergency, corn starch can be used temporarily, but requires frequent re-verification of consistency
- Contact the speech therapy department at a local hospital to enquire about resources
After an Aspiration Event
If the patient develops symptoms suggesting aspiration pneumonia during travel (fever above 38°C, rapid or laboured breathing, increased cough), go to the nearest emergency department immediately. Present the medical summary and SLP diet prescription in the local language to explain the patient’s history.
Frequently Asked Questions
Q: Is long-haul air travel (10+ hours) suitable for a dysphagia patient?
A: This depends on the patient’s overall medical condition, swallowing stability and caregiver preparation. Long-haul flight fatigue can reduce patient alertness, indirectly affecting swallowing safety. Discuss with the attending physician and SLP before booking to confirm travel suitability and identify necessary preparations.
Q: Can I carry thickener powder on a plane?
A: Thickener powder is generally permitted in carry-on baggage and is not subject to the 100 ml liquid rule, though some airport security stations may require additional screening of powder. Carrying the SLP’s English-language diet prescription as medical proof is strongly recommended. Place powder in a clear sealed bag for easier inspection.
Q: Will healthcare professionals overseas understand IDDSI levels?
A: IDDSI has been adopted in over 60 countries, including the UK, Australia, Canada, the US and parts of Asia. In these regions, speech-language pathologists and many other healthcare professionals are familiar with the framework. For destinations with lower IDDSI adoption (some Southeast Asian countries), bringing a bilingual illustrated IDDSI level card is helpful for communication.
Q: How do I verify food texture and drink consistency while travelling?
A: Pack a metal fork (in checked baggage for flights) for the fork pressure test on solid foods. For drink consistency, carry 10 ml syringes for the IDDSI syringe flow test. Both tools are small and lightweight. The fork pressure test requires no equipment beyond a standard dining fork — ask restaurant staff for one.
