I'm flying to LAX by Korean airline and from there to Cancun by interjet. But their schedules allow me only 2 hours for transfer. I wonder if I could make it on time? Cheers.
For international flights, you need to check your luggage two hours before - that's a hard limit.
Even if you'd travel with hand luggage only and in business class, with immigration and customs, you'd have only a small chance to make it.
Note that you lose your second flight, including its return trip, if you miss it - no refunds.
You should also consider potential arrival delays. For separate tickets, book at minimum a six hour difference, better eight hours. Or book it on one ticket, then it is the airlines problem.
