For now, it's just a waiting game to see if Bárðarbunga erupts anything more than a string of unpronounceable letters in its name. But even if it does, major delays seems far less likely.
"If there were to be a major eruption, it would not necessarily produce a high ash column, so the likelihood of interruption of trans-Atlantic and European air travel remains low," Open University geoscientist David Rothery told AP.
Anyone wanting to track potential eruptions can check out the Icelandic Met Office, which is offering daily updates on activity registering around the volcano. And aviation authority Eurocontrol in Brussels is providing airlines with up-to-date forecasts for potential travel changes.
But at present, it doesn't look like this volcano will be an ash hat by clouding up your travel plans.
