# In-Flight Internet Reality Check (2025): China Southern Airlines — Shanghai to Singapore

> Real-world speed test of China Southern Airlines in-flight Wi-Fi on Shanghai to Singapore route. Usable for lightweight tasks.

> ✈️ Tested on: China Southern Airlines  
> 🛫 Route: Shanghai → Singapore  
> 🕐 Duration: ~5 hours  
> 📅 Date: June 2025  
> 💰 Plan: Starter Tier – ¥159 RMB (~29 SGD / 21 USD)

In June 2025, I flew from Shanghai to Singapore with China Southern Airlines and tried their **in-flight Wi-Fi**. I opted for the _Starter Tier_, which promises internet access for the full flight at a flat rate of **¥159 RMB** (~29 SGD / 21 USD).

Despite my skepticism, the service was **stable throughout** the entire flight—surprisingly usable for productivity tasks that don’t rely on video or real-time collaboration.

### 🎓 Verdict: Usable for MBA Study

The speeds were far from impressive but more than sufficient for **lightweight study workflows**. I accessed course materials, completed quizzes, and followed reading assignments—all from my phone.

✅ Perfect for:

- Reading articles or PDFs
- Messanging
- Browsing course content

❌ Not ideal for:

- Zoom / Teams meetings
- Video streaming
- Large file transfers

### 🧠 TL;DR

If you're flying China Southern Airlines and debating whether to pay for Wi-Fi on the Shanghai → Singapore leg, here's my take:

> **For ¥159, it's worth it if your needs are text-heavy.**  
> Set expectations right—this is _functional_, not fast.
