Diabetic outraged after airline bans him from boarding with his Great Dane service dog because animal is too big
Matias Rodriguez, who has diabetes, says Aeromexico refused to let him board a flight from Vancouver to Chile with Logan, his Great Dane service dog, because the animal was too large. Logan is trained to detect changes in Rodriguez’s blood sugar and alert him to possible emergencies, so Rodriguez says travelling without him was not an option.
Rodriguez’s friend and translator said he had notified the airport and completed the required paperwork. Although Logan had flown to Vancouver without difficulty, Rodriguez was rebooked for the following day and again told there was no room; he offered to buy three seats together. Staff reportedly said a first-class ticket costing more than $3,300 would be needed, without guaranteeing Logan could board. Aeromexico’s guidance says it has no specific weight limit for service animals and allows larger animals to be assigned a seat by a bulkhead at no charge. Rodriguez has since bought a first-class ticket for 31 October as another attempt to travel.
In short
- Aeromexico reportedly stopped Rodriguez boarding with his Great Dane service dog.
- Logan helps alert him to potentially dangerous blood sugar changes.
- Rodriguez bought a first-class ticket for another attempt to fly.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Airlines have a duty to make reasonable arrangements for disabled passengers, and a trained medical alert dog may be essential to its handler’s safety and independence. Rodriguez says he completed the paperwork, offered to buy adjoining seats and was still told Logan could not board; Aeromexico’s published guidance appears to allow larger service animals a bulkhead seat at no charge, which supports questioning how the policy was applied.
The case against
Airlines must also manage cabin space and apply safety and accommodation rules consistently, including when a very large dog may not fit safely in the available seating or obstruct access. If staff reasonably concluded Logan could not be accommodated on that aircraft, they could argue that refusing boarding was necessary, while offering another flight or seating option; the reported account does not establish what operational constraints staff faced.
Explained simply
Diabetes can cause blood sugar levels to fall or rise to dangerous levels. Some people use trained service dogs to detect changes and alert them to a possible medical emergency. Matias Rodriguez says his Great Dane, Logan, performs this role for him.
Airlines have rules for carrying service animals, including arrangements for larger dogs to travel in the cabin. Aeromexico’s published guidance says it has no specific weight limit and that a larger service animal may be assigned a bulkhead seat at no extra charge. The dispute concerns whether Logan could be accommodated on Rodriguez’s flight.
Rodriguez says he completed the required paperwork and that Logan had flown with him to Vancouver. He says he was then unable to board his flight to Chile with Logan, despite offering to buy three seats together, and was told a first-class ticket would be needed. The case raises practical questions about how airlines apply their animal policies when a service dog is unusually large.
