Arriving on LH from DME to T2, next flight is in 90 minutes from T1 on AA, booked as separate tickets. Few questions:

- Does anyone have experience whether DME flights on LH arrive at bus gate or jet bridge?
- Would you recommend clearing immigration twice and walking from T2 to T1 or taking the shuttle that leaves every 20 minutes?

Will have hand luggage only, so no rechecking bags. Both flights are in J but I don't think it matters for immigration lines since there is no priority, only matters if we arrive at jet bridge so I can be one of the first people off the plane.
