Mexico has one major legacy airline since the demise of Mexicana de Aviación (MX), one minor carrier, allied with United Airlines, three international Low Cost Carriers that also serve the USA; Internet and Volaris have increased the U.S. cities they fly to in 2016 and 2017. There are some purely domestic airlines. Americans may access these (and the above) most often from TIJ / Tijuana International Airport for cost savings and the convenience of more direct routines. There are several regional and local airlines, not covered by this topic, such as AeroTucán, in this thread and Aero Banana in Quintana Roo.

Next week need to go from GDL to MEX for a couple of days and am trying to decide how to get there and back

GDL-MEX-GDL

Interjet and Volaris are about $100 R/T
VivaAerobus about $80 R/T

1 hour flight each way

Looks like Interjet has the nicest seats but otherwise I know nothing. If they are like Spirit here in the USA I will take the ETN bus even if it does take several more hours.

I flew Interjet about two weeks ago from PVR to MEX and it was about $20 more than the others, like your fare. However, their fare also included 1 suitcase which made the difference. Seat was very comfortable. Got a snack and a beverage enroute. No drama at all. (Also very ez to check in at the airport) Flight was about half full as well.

We've merged your query into the existing the thread, here. (Interjet offers ~34" pitch and seems pretty reliable.)

Well, just to let people in FT know how this works:

VB (Viva Aerobus): This is the Ryanair of Mexico, and very similar to NK (Spirit) in the USA. The charge for everything and have no selected seats (you need to buy the extra option that tells you the Group you will board with). They do Not let you print boarding passes with cheapest fare unless you pay more. So I would avoid this option if the other two LCC are $20 USD more expensive. You will end up paying those $20 USD in boarding group extra option and in Credti Card charge.

Y4 (Volaris): They are a normal Low Cost Carrier. They have snack and bar service on board for free and you can print your boarding pass and select your seats 72 hours before departure (if flying domestic). Service is similar to 4O (Interjet), being the only difference that they have 174 seats on their A320s vs 150 seats on Interjets A320s. They will also let you check a 15 Kg. bag and carry on a 10 Kg. bag included in the price of your ticket

4O (Interjet): Another normal Low Cost Carrier, and Y4´s principal competitor. They have similar good service as Volaris, as they also have snacks and bar for free and let you check in a 25 Kilos bag. You can print your boarding pass and select your seat before departure and the only extra they have vs. Volaris is the seat pitch, because they only have 150 seats in their A320s.

For me, Volaris is always cheaper than Interjet, so normaly Volaris gets my money on the MEX-CUN/TIJ/SJD routes. Volaris is always priced cheaper than even Viva Aerobus (for when I buy my tickets Apex 90, at least).

All in all, if you want to avoid the Mexican Spirit (Viva Aerobus), then you still have the mexican cuasi Jet Blue (Interjet) and the Mexican EasyJet (Volaris) LOL, which are for me the best comparison of airlines.

Interjet now has five Sukhoi Superjet 100-95s / Сухой Суперджет 100, with 15 more on order and 10 further options. 93 coach seats with 34" seat pitch, 1,894 mi / 3,048 km with max passenger payload - in addition to their 42 Airbus A320-200s (and they have 40 A320-200 neos on order).

This airline just came " on board" a few weeks ago. It has me excited because it services non-stop from Queretaro to some of the beach resorts like PV and ZIH.

And fares are reasonable.

Ya dunna read Airways magazine, do ya laddie? Ya dun beat me to it, but I've added it up in the main post anyway. Looks like Marfa Group has a new bairn.

looks promising, hopefully it wont be too long before they have lfights out of TLC or Puebla; dont blame them for wanting to stay away from MEX.

Si. That's the hub for nearly eveything else, so they might do well with smaller aircraft, sole source point to point flights where one does not have to connect in MEX (or in a few instances, Toluca).

So we need to fly from QRO to MEX to OAX. Tried the usual Delta and all and AeroMexico but curious if there are other domestic airlines in Mexico that are relatively safe and much used with good reputation?
On that note how safe is Queretaro now?
Thx

Any of the big Mexican airlines (Interjet, Volaris, Aeroméxico, etc) will be fine, although if you take the low-cost carrier expect to pay baggage fees and plan accordingly.

I have sadly never been to Querétaro, but everyone I know who has says it's a gem, and I wouldn't expect to to be any less safe than any other tourist destination in Mexico.

Update-

Queretaro was fantastic!. A pretty wealthy place, and we really enjoyed it. Regarding airlines, I would suggest stick to the Aeromexico or Aeromar as we saw horribly long lines on the others even at the gates, disorderly mess, just a free for all at the gates. We also did a recent trip all over Mexico -from PVR to Merida to Puebla and to Cancun. All were great except Cancun
Whilst on Cancun-some thoughts--
There is a taxi mafia that controls Cancun and they do not allow Uber to come near the airport or hotels. If you order Uber at a hotel, be discreet, sit in the front, act like it is your freind/relative. We were told by Uber drivers that they have been threatened by machetes by taxi drivers
On all accounts, avoid Comfort Inn at the Cancun Airport-it is a mess...the taxi mafia is very active there, the lobby is a mess, there is no breakfast, they fleece you off $$$$ and they will not give you a shuttle to the airport (they made some excuse and then we saw them harassing a woman for money to take her to the airport ). In addition the lobby is run by a few guys who have a counter there and are trying to sell all sorts of tours/extras very aggressively. The whole place is being run as though a group of people have taken over it. We were really glad we did not stay there for more than a night.
Regarding Airlines, we were quite happy with Aeromexico but we had to check in and pay for a bag ($30) even though we are Aviator card holders. We will be canceling that card soon.

By all means write the Comfort Inn headquarters about your stay. My guess is the hotel is in name only.....but experiences like this drag the whole corporate image down.
