Rapid Response Times
Safe Fly Express also offer unscheduled flights available with a minimum lead time of just three hours — perfect for genuine emergencies and last-minute requirements.
Engineered for Temperature Integrity
We don’t just hand your goods to an airline and hope for the best. We’ve specifically designed our air freight process around the physics of frozen food transport:
- Temperature-controlled collection and delivery in our own refrigerated vehicles (-12°C)
- Airport cargo terminal freezer storage before and after flight
- We fly the last flight at night — deliberately chosen to minimise tarmac thermal exposure during the warmest hours
- Typical tarmac standover is approximately 20 minutes, with nighttime ambient temperatures significantly reducing heat infiltration
- Destination-side freezer storage immediately upon landing
- Final delivery in refrigerated vehicles
Premium for a Reason
Air freight costs more than road transport, but when time is critical and product value is high, it’s the investment that protects your business.
Understanding the Temperature Profile
Transparency matters. Here’s exactly what happens to your product’s temperature environment at each stage of the journey:
| Stage | Temperature | Who Controls It | Our Monitoring |
|---|---|---|---|
| Collection in our truck | -12°C | Us (SANAS-verified Cold Watch) | ✓ Continuous |
| Airport cargo terminal freezer | Freezer storage | Cargo terminal operator | ✗ |
| Cargo scanning & handling | Brief ambient exposure | Cargo terminal operator | ✗ |
| Aircraft perishable cargo hold | -1°C to +3°C | Airline | ✗ |
| Tarmac loading/unloading | Ambient (~20 min) | Airline ground crew | ✗ |
| Destination cargo terminal freezer | Freezer storage | Cargo terminal operator | ✗ |
| Delivery in our/partner truck | -12°C | Us or delivery partner | ✓ Where ours |
The critical detail: The aircraft perishable cargo hold operates at -1°C to +3°C — not frozen temperatures. This is an airline standard, not something we control. Your product’s thermal mass is what maintains its frozen state through this leg of the journey.
This is exactly why proper freeze-down before dispatch is non-negotiable for air freight.
⚠️ Your Product Must Be Frozen Solid Before Dispatch
This is more important for air freight than any other service we offer.
Because the aircraft cargo hold operates at -1°C to +3°C (not -18°C), your product must have completed Phase 5 (Solid Cooling/Tempering) — uniform -18°C from surface to centre — before we collect it.
Products that are only frozen on the outside (Phase 3 or 4) will thaw during the air transport leg. No amount of good packaging or fast handling can compensate for inadequate freeze-down when the cargo hold is above 0°C.
Minimum freeze-down times before air freight dispatch:
- Small items (500g): 24–36 hours in freezer
- Medium items (2–3kg): 48–60 hours in freezer
- Large items (5kg+): 72–96 hours in freezer
Products with low temperature tolerance — including ice cream, frozen yogurt, gelato, and sorbets — require particular attention. These products show quality degradation rapidly if not fully tempered before dispatch.

We reserve the right to refuse goods that are not frozen solid at collection. This protects your product and other customers’ goods.
📦 Packaging Matters — Especially for Air Freight
Your packaging is the last line of defence between your frozen product and the temperature variations of air transport. With a cargo hold at -1°C to +3°C and brief ambient exposures during handling, good packaging isn’t optional — it’s what keeps your product frozen when the environment can’t.
Use quality cardboard boxes. We strongly recommend virgin double-walled cardboard for all air freight shipments. These provide the best thermal barrier and structural integrity during handling, stacking, and transport. Recycled, single-walled, or damaged boxes lose heat faster and are more likely to collapse — both problems that are amplified when your product spends time in a cargo hold above 0°C rather than in a -12°C truck.
If you’re using polystyrene boxes, they must include ice packs or gel packs and be packed completely full. Polystyrene without a cold source just slows warming — it doesn’t maintain temperature. Half-packed boxes with air gaps are particularly problematic for air freight where every degree of thermal protection counts.
Pack in a cold environment and seal boxes immediately. Packing at room temperature traps warm air inside the box that works against your frozen product for the entire journey.
As set out in our Terms and Conditions (Section 3), packaging is your responsibility. We cannot be held liable for temperature deterioration that results from inadequate packaging choices — this applies to all services but is especially critical for air freight given the temperature profile above.

How It Works
- Flight Coordination — We work with Safe Fly Express to book the last evening flight, optimising for minimum tarmac thermal exposure
- Temperature-Controlled Collection — We collect from your location in our refrigerated vehicle at -12°C
- Airport Cargo Terminal — Goods are transferred to the cargo terminal, scanned, and placed in freezer storage
- Loading — At flight time, goods move from freezer to cargo truck, to tarmac, into the aircraft perishable cargo hold (-1°C to +3°C). Typical tarmac standover: ~20 minutes
- Air Transport — Safe Fly Express provides rapid air cargo service
- Destination Handling — On arrival, cargo truck collects from aircraft and goods are placed into freezer storage at the destination terminal
- Final Delivery — Refrigerated vehicle delivers from destination airport to your location
- Confirmation — You receive delivery confirmation with temperature records for legs under our monitoring

Third-Party Carrier Terms
Important: Safe Fly Express, the airline, and cargo terminal operators are third-party service providers. Once your goods leave our refrigerated vehicle at the origin airport, they are in the care of third-party operators until collected at the destination.
As set out in our Terms and Conditions (Section 19):
- Third-party carriers operate under their own terms, conditions, and insurance
- We are not liable for loss, damage, delay, or temperature problems during the third-party portions of the journey
- Any claims for issues during air transit must be directed to the relevant carrier
- We will help you identify the responsible party and provide their contact details
We select our partners carefully — Safe Fly Express has a strong track record with perishable cargo — but we are transparent about where our direct control and liability begins and ends.

Typical Transit Times
- Same-day service: Collection to delivery within business hours (morning collection, afternoon delivery)
- Next-day service: Evening collection, next morning delivery
- Unscheduled flights: Available with 3-hour minimum preparation time
- Airport-to-door: Delivery completed within hours of landing
Transit times depend on flight availability, airport locations, and final delivery zone.
Pricing
Air freight pricing is premium and varies based on:
- Origin and destination airports
- Weight and volume of shipment
- Urgency (scheduled vs unscheduled flight)
- Time of booking
- Special handling requirements
For planned air freight shipments, advance booking can help optimise costs.
When To Choose Air Freight Over Road Freight
Choose Air Freight When:
- Time is absolutely critical (event tomorrow, emergency shortage)
- Product value justifies premium shipping costs
- Long-distance transport needed in minimal time
- Road freight transit time is unacceptable
- Product is time-sensitive (ultra-premium items with short shelf life)
Choose Road Freight When:
- You have 3–5 days for delivery
- Cost efficiency is the priority
- Shipment size is large (pallet quantities)
- Regular scheduled deliveries are acceptable
