I am planning a trip for early August from EWR to Ibiza. I explore different options with separate tickets but I think it would be best for me to keep the flying to United/Lufthansa thus will be connecting in MUC. United's flight from EWR arrives at the H gates and LH's flight to Ibiza departs from the K gates. The United app is extremely helpful in showing routine between the two gates but I still not clea whether I will have to clear immigration before boarding the flight to IBZ. Are there any immigration facilities at IBZ or will I have to go through immigration and collect my checked bag in MUC? The connection time is about 1.5hr which may be a bit too tight for me to be comfortable with. How does that sound?
