The London Airport level in Ball Travel is a challenging stage, with numerous passengers presenting various demands, making it difficult for players to cope and unsure of how to proceed. To help everyone pass this level smoothly, the following shares a guide on how to clear the London Airport level, explaining the preparation required beforehand and the techniques for completing tasks. If you're still unsure about how to get through, take a quick look below.

For the basic preparations, it's recommended that at the London Airport, you focus on upgrading the oven and can opener to reduce production time. It's also suggested to upgrade the juicer to its maximum level to ensure efficient beverage supply. Upgrading business class will increase the order capacity by 4, boosting the level's earnings. Other items like tray sets and compressors can be left unupgraded for now, while garbage bags only need to be upgraded to level 1 to avoid wasting resources.

When entering the level, it's advised to alternate between making two types of tea, prioritizing milk tea for the last row of passengers to minimize repetitive actions. When filling up with apple juice, first deliver orders that don't require juice to save time. For main dishes and side dishes, keep preparing English breakfasts and sliced bread.

These two ingredients are quite substantial, so having more prepared can prevent running out when needed. Potato wedges and honey beans should also be sent out in advance. If there are beans, use the can opener to process them before serving. When faced with the task of getting 10 smiles within 10 seconds, simply prepare the meals ahead of time.

Delivering 10 meals quickly at once will achieve this. If your speed is slower, you can choose to serve those requiring snacks and bread; the effect is the same. Finally, pay attention to using the compressor to handle full garbage bags to avoid occupying operational space.

The above is the guide for passing the London Airport level in Ball Travel. The main content shared includes the necessary preparations and some practical tips for gameplay. After understanding these, make sure to apply them in the game. Lastly, I hope everyone can successfully pass each level and upgrade their equipment.
