There is so much to say about Mercury retrograde and it's relationship to travel. For starters Mercury governs our intellect, buddhi, logical mind, communication, business and travel. It's not just about travel then - is it really?
If we understand that Mercury retrogrades about 3-4 times a year for about 2-3 weeks at a time, that mean it's highly likely that we may find ourselves travelling during that time. Retrogrades are about reviewing, reflecting and revising which can then inadvertently create disruptions. Therefore, whether we travel or not I feel as though the graha (planets) may have an effect on us in other parts of our lives not just travel.
I believe that we live in a modern world that may demand travel and not truly align with transits. So it's best to use the transits to inform us rather than create fear.

A few tips to keep in mind:
Expect for delays and disruptions: now there might not be many major disruptions but you can be alert if there are any and mentally prepare for acceptance around this.
Double check your travel details: make sure you check your flight details or however you are getting to your destination. You can organize everything for your upcoming travel in a document on the notes app or google docs for example.
Create a protection ritual: Airports carry a lot of anxious energy! (Mars, Mercury energy!!!) You may want to chant some mantras or mediation on the day of your travel to help calm your nervous system down (Mercury is related to our nervous system). You can even carry some crystals like black tourmaline to support you further.
Travel doesn't have to be completely avoided as we have to look at your individual birth chart to get the full picture of what's going on. You may be running a dasha that is activating travel for you! Or you might also already have mercury retrograde in your chart - this may make you more accustomed to deal with these kind of energies.
Wishing you all safe travels for your next time ahead and I hope you keep these in mind if you do end up travelling during Mercury Retrograde.
