As someone with a direct eyeball on tens of thousands of FedEx shipments each year through ShipYourReptiles, I can tell you that YES, this year is worse than any in recent history.
But IT IS ALL RELATIVE. In a normal day, less than 3% of packages will be late. In a crazy day of delays, maybe 5%, very rarely 10% of packages will be late (usually a Spring or late Summer storm in Memphis).
There have been a few times this year where weather has caused crazy delays and chaos in the system. There were two periods in 2015 where there were delays for perhaps 40% of air shipments. That was indeed a nightmare.
In one week in February, we paid out over $10,000 in late arrival refunds. Ouch! But that is what the SYR insurance is for...
UPS really isn't any better performance wise. They have the same statistical delays, less than 3%. They have their own weather and delay issues going through their hub in Atlanta, which is one of the busiest airports in the world.
One service or the other may be better for YOU, according to your location/region. But service wise they are statistically the same.
Rate wise, the base rate of FedEx is the EXACT same as UPS, to the penny, across all services. The discount you are able to secure on your particular account is what varies.
As mentioned, UPS doesn't allow snake shipments. They aren't friendly or supportive of reptile shipping at all. We are a FedEx company, but still, FedEx has an actual Live Animal Desk, and they are actively supportive of the reptile industry. They deserve your support.
It is incredibly frustrating when you have a late package, for sure. And there have been more storms and delays this year than in years past, but there is no simple solution or "go around" for that.
If you are using ShipYourReptiles and you have an issue or delay, contact us directly, not FedEx. With our relationship and volume, we swing a much bigger hammer with FedEx than you are able to on your own, and if something can be done, or expedited, we can make it happen.
