Frequently asked questions
Where is General Lucio Blanco International Airport (MMRX) located relative to the US border?
General Lucio Blanco International Airport, identified as MMRX, sits in Reynosa, Tamaulipas, just south of the Texas border. The closest reporting point tracked in FAA data is McAllen International, about 10 nautical miles north on a bearing of 357 degrees. Other regional fields nearby include Mid Valley, Moore Field, South Texas International at Edinburg, and Valley International, all within roughly 34 nautical miles. Its position makes it a natural entry or exit point for operators working the Rio Grande Valley corridor. Crews should plan cross-border coordination given the proximity to multiple US airports.
What is the runway length at MMRX?
MMRX has a single paved runway, designated 13/31, measuring 6,243 feet long and 148 feet wide with an asphalt surface. This is also the airport's maximum paved runway length, giving operators a clear reference for performance planning. The width of 148 feet is generous, accommodating a range of business and commercial aircraft. There is no secondary runway listed for General Lucio Blanco International Airport, so all traffic uses this single strip. Surface condition and load-bearing details beyond length and width are not part of the published data.
How much business aviation traffic does General Lucio Blanco International Airport handle?
General Lucio Blanco International Airport recorded 762 business aviation operations in 2025 out of 4,293 total cross-border operations tracked, according to FAA TFMSC data. Because the airport is in Mexico, these figures represent cross-border traffic as seen by the FAA rather than the airfield's full operational count. March was the busiest month for bizav activity with 122 operations, while June was the slowest with 35. This seasonal swing suggests operators should expect variable slot and ramp availability depending on the time of year. Dispatchers should treat these numbers as a cross-border traffic indicator rather than a total airport activity measure.
When is business aviation traffic at MMRX most concentrated?
Business aviation traffic at MMRX, or General Lucio Blanco International Airport, shows a clear seasonal pattern rather than an even monthly spread. March stands out as the peak month with 122 operations, well above the second-highest month, February, at 76. The lowest month is June at 35 operations, less than a third of the March figure. Operators planning trips into this Reynosa field should account for this concentration when estimating ramp congestion or scheduling flexibility. The FAA TFMSC cross-border data underlying these counts spans the full 2025 traffic year.
What temperatures should crews expect at General Lucio Blanco International Airport in summer months?
Summer conditions at General Lucio Blanco International Airport run hot, with average high temperatures peaking at 99.6 degrees Fahrenheit in August. July and June follow closely at 98.5 and 97.4 degrees, respectively. August also averages 30.0 days above 90 degrees Fahrenheit, meaning nearly the entire month sees extreme heat. These figures affect density altitude and aircraft performance planning for operations into and out of MMRX. Winter months are markedly milder, with January averaging a high of 72.8 degrees Fahrenheit.
