FedEx partner airline Mountain Air Cargo has formally asked the Federal Aviation Administration for regulatory relief, warning that key cargo services to Aruba, Curaçao, and Bonaire could be jeopardized without a waiver. The issue stems from the carrier's planned fleet modernization-replacing older ATR 42 freighters with larger ATR 72 aircraft-and a catch in FAA rules that makes the transition far more complicated than it sounds.
Here's what's happening, why it matters for your shipments, and how XMAE Logistics makes sure your goods keep moving no matter what the regulators decide.
What's the Problem?
Mountain Air Cargo currently operates its ATR 42 fleet under Part 135 regulations, which govern commuter and on-demand operators. Under those rules, the airline can legally fly overwater routes for up to three hours as long as additional safety requirements are met. That flexibility has kept FedEx cargo moving smoothly to Caribbean islands for years.
But when the airline tries to switch to its newer, larger ATR 72 freighters, things get messy. Those planes fall under Part 121 regulations, which apply to scheduled commercial airlines and impose stricter overwater flight limits-just 60 minutes of flying time over water unless the carrier goes through the costly and time-consuming process of securing Extended-range Twin-engine Operational Performance Standards (ETOPS) approval.
The catch? Aruba, Curaçao, and Bonaire lie only about 20 miles beyond the overwater limit set by Part 121 rules. Mountain Air Cargo laid it out plainly in its filing: "ETOPS approval would be required solely to accommodate an additional 20 miles of overwater distance to the destination. While we fully respect the regulatory framework and the safety protections it provides, the operational cost and administrative burden of maintaining a fully compliant ETOPS program is disproportionate relative to the incremental distance involved."
Flights to those islands are already packed-operating at 85% to 100% capacity on existing ATR 42s. Add in the fact that ATR has stopped producing ATR 42s in cargo configuration, and the airline has little choice but to transition to the larger, more efficient ATR 72s going forward.
Why Should You Care?
If you're shipping from China to the Caribbean or transshipping through the region, this isn't just airline gossip. FedEx feeder carriers like Mountain Air Cargo are the backbone of regional cargo networks, moving goods that don't make economic sense for large jet aircraft into smaller island markets. Without regulatory relief, capacity to several key Caribbean destinations could shrink at a time when demand is already strong.
FedEx has signaled its confidence in the direction-the company ordered 10 additional ATR 72-600 freighters for deployment among its regional partners last year. But fleet upgrades mean nothing if regulatory hurdles ground the planes before they even take off.
How XMAE Logistics Helps You Stay Ahead
At XMAE Logistics, we don't wait for disruptions to happen before we start looking for solutions. As a government-licensed, IATA-, FIATA-, FMC-, and NVOCC-approved freight forwarder, we've built a global network of over 100 overseas agents to keep your supply chain moving no matter what.
Here's how we handle situations like this:
Multi-carrier alternatives. When one carrier's capacity gets squeezed, we tap into our relationships with multiple top carriers to reroute your cargo and keep delivery timelines intact. You're never locked into a single lane or partner.
Mode flexibility. Air freight facing constraints? Sea freight might be the smarter move, depending on your timeline. Or a multimodal approach that mixes both. Our team analyzes the trade-offs in real time and recommends the option that truly works for you-not just the one that's easiest to book.
Customs and regulatory expertise. Shifting routes often means dealing with new customs requirements, documentation changes, and regulatory hoops. Our team handles all that behind the scenes, so you don't have to track which island now requires which paperwork.
Real-time visibility. When carriers make sudden changes, you need to know exactly where your cargo is and what's happening next. Our centralized tracking platform gives you a clear, real-time picture of your shipments, with proactive updates when conditions change.
Looking Ahead
The FAA hasn't made a decision on Mountain Air Cargo's waiver yet. But regardless of how the regulatory dust settles, one thing is clear: supply chains that rely on a single carrier or a single route are the ones that get hurt when surprises pop up. At XMAE Logistics, we've spent years building a diversified, resilient network so you don't have to cross your fingers and hope for the best.
