One of the best ways to build long-term wealth is through a buy-and-hold investing strategy.

By selecting high-quality ASX 200 blue chip shares and allowing them to compound over time, investors can benefit from both capital appreciation and dividends.

This approach avoids the pitfalls of short-term market timing and takes advantage of the long-term growth potential of strong businesses.

With this in mind, let's take a look at two ASX 200 blue chip shares that analysts believe are great buys and are forecasting double-digit returns over the next 12 months. They are as follows:

Flight Centre Travel Group Ltd (ASX: FLT)

The first ASX 200 blue chip share that analysts have their eyes on is Flight Centre.

It is a leading travel company that operates under the well-known Flight Centre brand, as well as Aunt Betty, Corporate Traveller, FCM, Stage & Screen, and Travel Associates.

The company has faced some headwinds in recent months and recorded a softer-than-expected start to FY 2025. This has put pressure on its share price, presenting what analysts at Macquarie see as an attractive buying opportunity.

Macquarie feels that its shares are undervalued at current levels and has put an outperform rating on them with a price target of $22.34. Based on the current Flight Centre share price of $17.83, this implies potential upside of approximately 25% for investors over the next 12 months.

Goodman Group (ASX: GMG)

Another high quality ASX 200 blue chip share that analysts are backing is Goodman Group.

It is a specialist global industrial property and digital infrastructure company. The business focuses on owning, developing, and managing high-quality, sustainable properties that are close to consumers and play a critical role in the digital economy.

Goodman's strategy has proven highly successful over the past decade, with the company delivering consistent earnings growth and rewarding shareholders in the process. One of the key drivers of this success is its exposure to high-growth sectors such as e-commerce and data centres, both of which require significant logistics and industrial infrastructure.

Morgan Stanley is particularly optimistic about Goodman's outlook, citing its strong pipeline of projects, including data centre developments that will benefit from the rise of artificial intelligence.

The broker currently has an overweight rating on its shares with a price target of $40.00. Based on the current Goodman share price of $36.34, this implies potential upside of around 10% over the next 12 months.
