Lille itself sits 38 miles from Brussels and under an hour from Paris by high-speed rail, making it a strategically underrated entry point for business travelers covering multiple northern European markets in a single trip. Arriving rested after a business class transatlantic crossing — rather than cramped in economy — has measurable impact on productivity, especially when meetings begin within hours of landing. The math on upgrading becomes straightforward when private fares bring the cost closer to premium economy retail pricing.
